1
Monkey badly wants to change his life.
2
He is tired of where he is, tired of his physique, and tired of how his mind is not his friend.
3
He goes through cycles of being extremely motivated and locking in, then falling off, then locking in again, and falling off.
4
Years have gone by like this, and for some monkeys their entire life goes by without them breaking the habit of being their worst selves.
5
It is terrible.
6
So what can monkey do?
7
Monkey can self -educate.
8
Through self -education, monkey can understand why he's stuck in this cycle and break out.
9
He can learn the skills of charisma, of discipline, and of detaching from his emotions,
10
as well as countless other skills that will completely change his wealth, relationships, and quality of life.
11
So here's how monkey self -educates.
12
The algorithm that controls behavior.
13
Reward prediction error theory is the leading theory of how the monkey brain handles learning.
14
If monkey understands this theory he'll understand how his brain works
15
and he'll understand what he needs to do in order to self -educate and start changing his life.
16
Here it is explained using a simple story.
17
Monkey has just found a tree.
18
Monkey has never seen this tree before but it bears low -hanging yellow fruit
19
and seeing that yellow fruit has just caused his dopamine levels to spike because he anticipates a reward.
20
This is because monkey's brain has learned from experience that yellow fruit means yummy sweetness.
21
An increase in dopamine does something to monkey.
22
He becomes more motivated to pursue the goal of getting the fruit.
23
Dopamine is in fact the molecule of pursuit.
24
Any increase, even small, above
25
Monkey's baseline level makes him more motivated to pursue things.
26
So two minutes later, like a well -trained dog, Monkey has climbed the tree and snatched the fruit.
27
He eagerly bites into it and finds out it's a fucking lemon.
28
What a disaster.
29
Monkey's day is ruined.
30
But lemons aren't that bad.
31
Eating a lemon when expecting a lemon is fine.
32
So why is this such a disaster.
33
This is where dopamine comes in again.
34
Dopamine is not a reward detector, it is a surprise detector.
35
The brain does not care about the reward, it cares about whether it was a surprise or not.
36
Once Monkey fully understands this, he'll realize why he always goes through this cycle of locking in and falling off,
37
and he'll understand how to fix it.
38
So let Monkey explain.
39
By the way, Monkey built a habit game for the monkey brain.
40
It helps you fight distraction.
41
You can block all brain or apps until a habit is completed for the day.
42
Now you have to earn your scrolling in the morning.
43
It makes building habits fun.
44
You earn bananas every time you show up, which can be used to buy in -game items and build a monkey paradise.
45
And it gives you small short -term wins, which are key to not giving up, according to science.
46
Try it for free by tapping the link in the pinned comment.
47
Now back to the video.
48
Dopamine helps monkey form an accurate model of reality.
49
It does this through predictions.
50
In this situation monkey's brain predicted a sweet banana flavor and got a horrible sour lemon.
51
The prediction was badly wrong and so monkey's dopamine creates a negative prediction error signal.
52
His dopamine levels drop below baseline and this change in dopamine is how monkey's brain learns.
53
It's not just negative predictions either.
54
If the lemon had tasted exactly as monkey had predicted it to taste there would be no change in his dopamine levels.
55
No prediction error signal because monkey's brain correctly understands the world so there's no updates needed.
56
And if the lemon tasted like one of grandma monkey's delicious cakes then he'd be equally surprised
57
but in a good way and here his brain would encode a big positive error signal by spiking his dopamine above baseline.
58
Now imagine that monkey didn't find a lemon tree and imagine that he discovered online porn, cigarettes or TikTok.
59
The prehistoric monkey brain would not be able to comprehend such levels of dopamine.
60
In fact like an 18th century peasant shown pornography he might fall over and die of shock.
61
This is because addictive stimuli like porn, scrolling and nicotine produce reward prediction error signals far larger than anything natural.
62
And this is a problem.
63
A massive reward prediction error is a massive learning signal.
64
It tells the brain that this is the most rewarding thing in the environment
65
and that if possible do more of this thing.
66
It's why experiments show that rats if given enough food, water and cocaine will skip the food and water and consume pure
67
Colombian white until they die.
68
Modern addictions are nearly all caused by hijacking the dopamine system and constant exposure to these addictive stimuli raises monkey's dopamine baseline.
69
As the baseline goes up he needs more in order to satisfy him.
70
He needs to call up his friend
71
Pablo to get the purest
72
Colombian marching powder he can find because this UK stuff won't cut it anymore.
73
His algorithms start noticing that cat videos aren't holding his attention and start feeding him more graphic, shocking and sexual content.
74
He types the craziest search terms into Pornhub because regular in and out action does nothing.
75
Monkey needs more and more stimulation just to feel normal
76
and it's at this point that natural rewards like learning a programming language
77
or an instrument or mastering a sport are no longer enjoyable.
78
They have become negative prediction error signals.
79
So Monkey has found out his answer.
80
He can't self -educate
81
because his indulgence in high stimulus behavior has caused his dopamine system to create a model of the world in
82
which self -education is always disappointing.
83
Well this is awful news and a big wake -up call for Monkey.
84
It explains why he can never change his life despite wanting to so badly.
85
It explains the cycle of locking in, falling off, locking in again and falling off.
86
It explains why years have gone by without
87
Monkey being able to break the habit of being his worst self.
88
So how does
89
Monkey fix this?
90
The uncomfortable truth is that
91
Monkey already knows the answer to this question.
92
He's watched enough self -improvement content to know what to do.
93
Sleep, exercise, diet, quitting social media, understanding habit loops so that friction can be introduced.
94
These are all the tactics and Monkey knows these but the thing is, like with a lot of addicts,
95
they only quit when the pain becomes too much to bear.
96
Too much failure, sadness, and depression makes them decide that enough is enough.
97
So Monkey has got to sit down and be honest with himself.
98
He's got to imagine in as much detail as possible what his future looks like if he continues.
99
He's got to picture how much regret, sadness, and disappointment will fill his heart if he continues like he is.
100
Because it's this realization that might finally cause him to change.
101
So Monkey will do it right now.
102
For the next hour if possible he will turn off all technology.
103
He will grab a pen and paper and he will think about his future.
104
What loved ones does he lose if he continues like this?
105
What does his day -to -day look like?
106
Is he stuck in a boring job that he hates.
107
What does his physique look like?
108
Is he in good shape, loving life, running around, playing sport and feeling healthy or is he aching, fat, depressed and overweight?
109
Monkey will sit and think about his future
110
and try to conjure up enough pain that he decides right there to change his life.
111
Fixing his dopamine will be Monkey's toughest battle but it will be so worthwhile.
112
Stay monkey.

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。
