If you've ever felt stressed,
2
overwhelmed, unsure where to go,
3
lost, overreactive, or just not happy and not satisfied with how things are going,
4
then keep watching this video.
5
With these three simple strategies that I'm going to talk through,
6
you can literally reprogram your mind's default operating system to rewire your brain for success
7
or neuro hack your way to being happier,
8
feeling more content, and also feeling more free to really fulfill your potential without any self-sabotaging thoughts.
9
If you're new here, my name's Izzy,
10
I'm a Cambridge graduate and a doctor.
11
And without further ado, let's dive in.
12
In this video, I'll firstly break down the science of neuroplasticity
13
and explain what this is and how this is the key to unlocking our own minds.
14
And then after that, I will dive right in to the three strategies that you can implement starting today.
15
Also, as a companion to the first step in the three steps,
16
I have created a meditation resource guide pack completely free of charge.
17
And it includes an exclusive guided meditation by me and all my favorite resources for it.
18
So if you're interested in checking that out,
19
then I'll leave a link down below in the description.
20
Again, completely free.
21
So up to you if you'd like that as a companion to this video.
22
Let's start with neuroplasticity.
23
Neuroplasticity is our brain's lifelong ability to change
24
and adapt through growth of new neural connections and reorganization or down regulation of existing ones.
25
Essentially, your brain can rewire throughout your whole life.
26
It's not true that our brains are fixed at all.
27
People used to think that after childhood, brains became more fixed now we know from the science that actually that's not true.
28
And for literally our whole lives,
29
so it's never too late,
30
our brains can change and rewire in response to our environment and our inputs.
31
This links into something called Hebbian learning,
32
also known as Hebb's theory or Hebb's law,
33
which is actually something they taught us about in medical school,
34
which can essentially be summarized as neurons that fire together, wire together.
35
Essentially, neural pathways that are used more frequently get strengthened and it's easier for them to fire again next time.
36
On the other hand, neural pathways
37
that are neglected not used start to wither away over time and become a little bit more defunct or difficult to use.
38
An analogy for this that I love and find is really helpful is the idea of forging a path through the jungle.
39
So if you imagine an overgrown jungle and you want to break a path through it,
40
you need to fight your way through the vegetation.
41
And the more that you tread down this path through the vegetation,
42
the clearer the path actually becomes and the easier it gets to use over time
43
because you cleared away some of this grass this time,
44
you've trampled it, so there's a clearer and and clearer path there's less vegetation over time.
45
On the flip side if you don't tread down
46
that path for a long time it starts to become more and more overgrown,
47
obstructed and difficult to use over time
48
because the vegetation kind of grows back in and makes the path more difficult to walk down.
49
And a very similar thing is true of the brain.
50
So the neuroscience behind rewiring our brain is that we need to practice the neural pathways that we want to encourage.
51
The ones that help us to take steps to become our higher self,
52
become the person that we want to be and avoid feeding any neural pathways that we actually don't want.
53
So those ones that self-sabotage us or that hold us back from fulfilling our potential.
54
So one of the things that actually down regulates neuroplasticity
55
and makes it more difficult to rewire our brains is being under a constant state of stress.
56
This is why actually when we're feeling relaxed
57
and comfortable we actually do our best learning
58
and our brains can change more rapidly because it's more open to change rather than being in a stressed state.
59
There's a whole bunch of other things that affect neuroplasticity.
60
I could include those in a future video if you're curious
61
so let me know if you'd like me to talk more about this topic.
62
Also if you're enjoying this video so far you might enjoy my newsletter which is called Letters to My Younger Self.
63
You might want to check it out,
64
I'll leave a link down below.
65
And I actually develop a lot of my ideas in an app called VoicePal
66
which is one that I've actually helped to build
67
which is essentially an app where you can hit record and you just start speaking into the app.
68
Start with the seed of an idea
69
and then the AI will transcribe what you've said
70
and then ask you follow-up questions to prompt you to develop and deepen your thinking around an idea.
71
And so this is a way
72
that I find is really helpful for me to explore my own mind the way that I'm thinking about things.
73
And for me personally is often how I create content
74
because I will have all these ideas and I want to expand them and develop them.
75
I want my content to flow from me,
76
but essentially VoicePal creates these brainstorming structures and frameworks
77
that prompt me to be more creative and to tap into my mind more fully.
78
If you're interested in trying out VoicePal,
79
you can try it completely free.
80
So back to the video.
81
Let's dive in to the three C's of brain change.
82
Number one is cultivation, and this is actively developing new neural pathways through meditation and visualization.
83
This means actively working on the quality of our mind through generating certain states of mind
84
which over time and with practice become easier and easier to access.
85
For me personally, I've been meditating regularly for around five years now
86
and I can tell you without a doubt
87
that there is no single habit that has changed my life more completely than meditation.
88
I know that sounds grandiose but it's really really true
89
and there is so much strong data and evidence
90
that backs up the power of meditation to create change in our minds
91
and since our minds literally create our reality
92
and create they form the way
93
that we respond to the world it's an extremely fundamental way of reprogramming our responses to things
94
when i initially started meditation i actually found it really difficult to connect to
95
and i was like am i doing this right kind of sitting here trying to focus on my breathing
96
but i keep getting distracted and I don't feel like this is particularly effective.
97
And that's very natural, especially if you're starting out meditation.
98
So if you're new to meditation and you're having this experience when you're trying to meditate,
99
don't worry, trust in the process,
100
because it makes sense if we think about it from a neuroplasticity perspective,
101
where it's difficult to tread these new pathways of mindfulness, focus, equanimity, compassion.
102
It's difficult to train this muscle when we haven't already trod this path very clearly,
103
and these neural pathways to create that state of mind are just really not developed.
104
But the good news is that over time it really really becomes easier, I promise.
105
And so every single time just you showing up and putting in the effort is a form of progress.
106
Even if you can't notice the progress on a day-to-day level,
107
you will notice this progress over time.
108
Some of the numerous studies that have found benefits to meditation,
109
one 2012 study in particular found that on fMRI scans,
110
which essentially is an MRI scan looking at the function of the brain
111
and the kind of activity occurring in the brain showed
112
that the changes in brain activity in people who have learned to meditate hold steady even
113
when they're not meditating so this is in terms of the actual function of the brain
114
and the areas of the brain
115
that are activating the lead scientist de bord took before
116
and after scans of 51 subjects who learned to meditate over
117
the course of two months she scanned them not only
118
while they were meditating but while they were performing everyday normal tasks
119
and the scans found that these changes were actually persistent even when they were just doing everyday tasks,
120
showing that the benefits and the functional changes in the brain,
121
this rewiring that we're talking about,
122
actually persists even when you're not meditating.
123
And another 2009 study compared people who meditate with people who don't meditate on lots of different measures of psychological well-being.
124
Overall all of the studies and also my personal experience and
125
so many people's anecdotal experiences all align
126
that meditation is a really powerful fundamental way to change our brain's structure
127
and change the way that it works in a default pattern.
128
There are lots of different styles of meditations
129
and some of them are classic mindfulness meditation but other types
130
that I find go a little bit deeper include insight
131
or vipassana style meditation and also metabhavana meditation which is focused on developing compassion.
132
For me in particular metabhavana meditations focused on developing loving kindness and compassion for yourself and others.
133
Metta essentially means loving kindness or you can also translate it as compassion and bhavana means cultivation of.
134
So metta bhavana literally means the cultivation of loving kindness.
135
And the first time that I sat to do this kind of meditation I had such an intense experience.
136
It was actually like it felt like a huge emotional release because the first stage is actually generating a sense of metta,
137
of loving kindness for yourself because if you can't generate it for yourself it's hard to generate it for other people.
138
And so then when I tried to sit there and generate this sense of loving kindness for myself,
139
using verbal prompts like may I be well,
140
may I be happy, may I be free from suffering I just suddenly burst into tears
141
and I was like tears streaming down my face as there
142
was suddenly this like huge emotional release inside me where I realized
143
that I lived a lot of my life not necessarily showing compassion towards myself
144
or having loving kindness towards myself and so then over the several months
145
that followed I would regularly practice metta bhavana meditation and gradually like developed this feeling of love for myself,
146
which I'm still working on every single day.
147
But having that practice gave me a way to work with the muscle of my mind
148
and rewire it to be more self-compassionate.
149
And that's ultimately allowed me to be more compassionate to other people as well.
150
So if I were to talk to myself as a beginner in meditation,
151
I would have thought that meditation was only one thing.
152
But actually meditation is an approach to actively working on and cultivating our mind,
153
which means that we can really cultivate in many different directions
154
and it can achieve so many different things depending on the kind of meditation that you do.
155
As I mentioned near the start of this video I've created
156
a completely free resource pack for all the tips for beginning and meditation,
157
all my favorite resources including an exclusive guided meditation
158
that I recorded for you guys in case you'd like to listen to
159
that so you can get that completely for free down in the description below
160
because I genuinely think that the world would be a better place
161
and everyone would be happier and more connected and loving to themselves
162
and others if meditation was more widespread so
163
that it's something i'm really passionate about getting people involved in trying hence why i've put together all this pack
164
and just making this video i know i go on about meditation quite a bit on this channel
165
but i'm just hoping that
166
if i can inspire at least one person to pick up meditation
167
and help them on
168
that journey towards working actively on their mind all of this
169
will be worth Another thing I mentioned in this first section of cultivation is visualization.
170
And visualization is kind of like weightlifting for your brain.
171
A 2003 study found
172
that visualizing doing a task actually triggered similar activity in the
173
same brain regions of actually doing the physical performance of the task.
174
And so by very clearly visualizing yourself doing something,
175
you strengthen those neural pathways and ultimately physically change your brain.
176
The second C of brain change is consumption.
177
And by consumption, I mean content consumption.
178
Our brains literally get trained on our environment and our inputs, our stimuli.
179
And so our content diet,
180
the things that we absorb from around us,
181
has a huge impact on actually what kinds of things our brain learns to focus on
182
and what kind of connections we are encouraging.
183
If you're watching junk from the algorithm that's just being spewed out at you,
184
unintentionally just getting passively fed this content,
185
that is actually shaping your brain.
186
And so if you're watching content which is triggering comparison with others,
187
or like an over focus on material goods,
188
or just essentially something that you don't actually want to train your brain on,
189
you will unfortunately be training your brain on that kind of content.
190
On the flip side, if you actively choose wholesome,
191
educational, inspiring, uplifting content to feed your mind with,
192
your mind will gradually grow to reflect that.
193
It's a fact of the brain that what we focus on gets magnified and the content that we consume trains our brain,
194
which is why I'm so passionate about carefully curating our mental inputs through our content choices.
195
So for me personally, I used to follow a bunch of celebrities
196
or people who would post about an unrelatable lifestyle or had an unrealistic physique,
197
whether they had had either plastic surgery or edited their photos
198
or were just really like a kind of top one percent physique or they were showing off really materialistic goods,
199
showing off their Birkin bags or luxury brands.
200
And at some point after starting my meditation journey,
201
because at that point I became much more self-aware of the contents of my own mind,
202
I realized that these were actually having quite a negative impact on my brain.
203
They were leading to feelings of comparison,
204
unhelpful mimetic desire, essentially taking on desires that I didn't necessarily have in myself,
205
and feelings of dissatisfaction with my own life,
206
looking at this highlight reel of all of this flashy lifestyle,
207
and I could really see how this was leading to a more unhappy mental landscape.
208
So a couple of years ago,
209
I actually decided to curate my content consumption diet and take control,
210
take the reins of it.
211
Just like a physical diet and you are what you eat
212
and and all of that your mind is growing
213
and is trained based on what you feed it the way i approach this now is
214
that whenever i see a piece of content i put it through my good mental nutrition filter
215
which is essentially asking myself is this content supporting my mind to grow in the way
216
that i'd actually really like it to
217
or is it kind of doing the opposite and
218
so now i primarily follow accounts that fall into a couple of buckets so whether that's wholesome content or inspirational motivational content,
219
educational content, and on the flip side anything that leads to kind of unwholesomeness or unhappiness,
220
I just click the show less of this or mute or unfollow and just remove that from my content diet.
221
So a good action point here is to try to build
222
in this good mental nutrition filter each time you use social media
223
and when you're selecting the kinds of people that you want to follow.
224
The third C of brain change is conditioning.
225
This essentially embodiment practices.
226
For me, I love to have some affirmations
227
that I can come back to that remind me to be positive
228
and remind me to practice the muscle of those positive pathways
229
that ultimately are leading me to become the person I would like to be.
230
Affirmations I find are less powerful if you don't actually believe what is on the thing could potentially be true.
231
There needs to be a seed of I could believe this to be true
232
and also there needs to be some kind of physical engagement with it.
233
So recently, because I am currently pregnant and I am coming up to the birth of our baby,
234
I have been actively building in more positive affirmations around pregnancy and also birth.
235
Birth is a very scary process throughout almost our whole lives.
236
We're trained that birth is a really scary process and very painful.
237
And so I'm kind of using affirmations
238
and positive stories to try to neutralize some of this and try to rebuild some positive images around birth.
239
So for example, one of these positive birth affirmations is that my baby is the perfect size for my body.
240
And this is to help to create neural pathways
241
that try to counteract the fear of what if my baby is too big for my body?
242
I need to have all these interventions to get the baby out
243
or the baby gets stuck or all of these unnecessary anxieties that don't actually help me in the moment.
244
And I don't know whether they're true or not.
245
For most people, their baby is actually a perfectly fine size for their body
246
and they're able to give birth just fine with no issues.
247
So it's almost like this conditioning around birth that I currently have
248
or previously had was unhelpful for the kind of way that I want to show up and respond to the situation,
249
given that it's such a low likelihood that these issues will even come to pass.
250
They're looming way larger than they should in reality.
251
Another way that we can really cement a more positive neural pathway in place is through power poses
252
and embodying confidence, embodying positivity.
253
One meta-analysis, which included almost 10,000 people in this study,
254
found that when the participants took power poses or upright positions,
255
they felt better and were more confident than when they took contractive or hunched body positions.
256
And this was true across men and women.
257
This was a robust study that really shows that the way
258
that we show up in the world in terms of our posture,
259
our body position, really affects our internal feeling.
260
So one example from my life is
261
when I was about to do a live session for 19,000 people on how to do a vision board.
262
Beforehand, I didn't let myself hunch over.
263
I wanted to sit up,
264
shoulders back, upright position, bit of a smile on my face,
265
transmuting any fear into excitement,
266
or at least trying to because the main difference between fear and excitement is just a smile.
267
It's just a smile and how you show up physically in the world
268
and that can really change how you feel about something
269
and train your mind over time to follow on from
270
and take these cues from your body and really cement in
271
and condition yourself to to default towards internal feelings
272
which then lead to behaviors that are more in line with the person that we really want to become.
273
And if you liked this video I think you might like this video over here
274
which is where I talk about the neuroscience of vision boarding
275
and how to practically apply it in a really powerful way to achieve your dream life
276
so you can check that out over here thank you
277
so much for watching as always take care of yourself and i will see you in the next video bye

このビデオで話す練習をする理由は？
このビデオでは、脳を成功に向けて再配線する方法についての科学が紹介されています。あなたが感じているストレスや不安、満足できない日々を乗り越えるための英語スピーキング練習として最適です。このビデオを通じて、自己改善や自信を高めるためのヒントを理解しながら、実際の会話を模倣することができます。シャドーイング技術を使って、講演者の口調やリズムを真似ることで、自然な英語の流れを身につけることができます。
文法と表現の文脈
- neuroplasticity（神経可塑性）: 脳がどのように変化し適応できるかについて語るこの表現は、学習や成長に関連する会話の中で重要です。
- foundational operating system（基本的な動作システム）: 参加者が自分を再プログラムする方法について説明する際に使われ、このコンセプトは英語学習における自己改善に関連しています。
- neurons that fire together, wire together（一緒に活動するニューロンは結びつく）: これは、英語学習の際にも実践的に応用できる基本原則です。繰り返し行うことで、習慣が形成されることを示しています。
よくある発音の罠
このビデオの中には、英語学習者がよくつまずく発音やアクセントがあります。特にneuroplasticityのような専門用語は、音の流れが非常に滑らかであるため、注意が必要です。特に「ー」と「プラスティシティ」の部分が連結する際、リズムを意識してシャドーイングすることで効果的に習得できます。
また、Hebbian learning（ヘッブ学習）という用語も、発音の練習に役立ちます。このような難しい言葉を繰り返し練習することで、自信を持って発言できるようになります。最終的には、これらの技術を駆使することで、英語シャドーイングを用いて実践的なスキルを向上させることが可能です。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
