1
By providing space for constant evolution,
2
we can all transform how we view ourselves and the world around us.
3
Bear with me, everybody.
4
I'm going to start off today on a little bit of a heavy note,
5
but I promise things will lighten up.
6
The dots on this screen represent an adult life in months in months,
7
assuming a life expectancy of 90.
8
So if you're 18 years old right now,
9
this is an optimistic estimate of the months that you have left.
10
Take a second to take that in.
11
Probably not as many as you would expect.
12
And I'm sorry to say that it does get worse
13
because about a third of that time is going to be spent sleeping.
14
On average, 126 of those months will go to school and your career.
15
About 18 will be spent driving,
16
36 cooking and eating, 36 doing chores and errands,
17
and about 27 in the bathroom and taking care of personal hygiene.
18
So that leaves you with 334 months, optimistically, for everything else.
19
So this is where you tick the boxes on your bucket list.
20
This is where you pursue your passions and travel the world and leave your mark.
21
How you spend this time is going to determine the quality of your life.
22
But this time isn't just something that you spend,
23
it's also something that you invest.
24
Because what you do with it will quite literally determine the kind of person you become.
25
The body, mind and character that you will have in the future are being actively shaped
26
by how you choose to use your time today.
27
So take a second and ask yourself,
28
what do you want to do with that free time?
29
What things do you want to do that you haven't done?
30
Who do you want to spend that time with?
31
What is worth investing it in?
32
Now, I would be willing to bet that scrolling through TikTok,
33
binge-watching Netflix, and playing video games probably did not come to mind.
34
But today, the average 18-year-old in the United States is on pace to spend
35
93% of their remaining free time looking at a screen.
36
That is not counting time for school.
37
So, wrap your head around how sad that is.
38
Imagine getting to the age of 90,
39
seeing this visualization of how you spent all your time after the age of 18,
40
and thinking about all the things you could have done that you did not do because you got distracted.
41
And I also want you to ask yourself,
42
What do you think over 26 years of screen time would do to you?
43
What is that an investment in?
44
How would it change you?
45
It's well established that there's a link between high screen time and mental health issues such as depression and anxiety.
46
But recently, we've started to unveil the cognitive consequences of excessive tech use as well.
47
When we're staring at our screens,
48
we are constantly switching our attention between different pieces of information.
49
The average TikTok is about 15 seconds long,
50
and over 55% of web pages are viewed for 15 seconds or less.
51
And if you're switching your attention every 15 seconds for an average of 8 hours and 39 minutes a day,
52
you are training yourself to become chronically distracted.
53
Think about what that will do to your career,
54
to your relationships, and to your ability to pursue the things that matter most to you.
55
Unfortunately, the consequences of screen time are not limited to our mental health and our cognition,
56
because every social media platform carries a message that affects what we believe.
57
They influence the way we see ourselves and the way we see the world purely based on how they are designed.
58
Instagram inherently says that your worth is largely defined by what you look like and what you do on vacations.
59
It compels you to capture all the most meaningful moments of your life on camera
60
and share them with your entire social network.
61
And it implicitly says that it's more valuable to have a thousand people that will give you transient social approval
62
than a few that deeply care about you,
63
even when it's not your best day.
64
Snapchat inherently says that the quality of our relationships is best measured by the frequency of our communication,
65
regardless of what we're actually saying.
66
You get a point added to your Snapchat streak
67
even if you just send a picture of the side of your face with the captioned streaks.
68
Twitter says that anything worth saying can and should be reduced to an arbitrary number of characters.
69
It says that the world is black and white,
70
that it's more important to be updated about everything than deeply informed about anything.
71
And when you start to compare the messages these platforms are sending with those of technologies from the past,
72
you begin to get a sense of what we might be losing.
73
Because the inherent structure of a book says that the world is complex and it takes time to understand.
74
It compels us to walk in the shoes of other people and see things from their perspective with context.
75
And it forces us to focus on one train of thought for an extended period of time,
76
which nurtures our attention.
77
And the letter tells us that our communication doesn't need to be frequent.
78
It just needs to be deep.
79
So when you factor all that in,
80
it quickly becomes clear that the opportunity cost of this screen time is impossible to calculate.
81
And I have never shown this visualization
82
to anyone that actually wants to spend 93% of their remaining free time staring at a screen.
83
So there is a stark difference
84
between how much time we say our screens are worth and how much time we actually give them.
85
And it is critical to realize that is not an accident. That is by design.
86
It's a consequence of a business model that has incentives which are fundamentally misaligned with your well-being.
87
Because you are the product that social media sells.
88
These services are free because they are monetizing you.
89
They profit by helping advertisers change your future behavior,
90
whether that be where you spend your time,
91
how you spend your money,
92
or even who you vote for.
93
In order to do that,
94
they have to do two things.
95
They need to figure out
96
which ads are going to influence you by collecting as much data about you as they possibly can,
97
and then they need to show you as many of those ads as possible.
98
So social media is free because you pay for it with your time.
99
Their profit is directly linked to how long they can get you to scroll.
100
And every social media platform is in a battle with each other to capture as much of your free time as possible.
101
So let's run a thought experiment.
102
I want you to ask yourself,
103
how much would you pay for your favorite social media platform platform if it charged you a monthly subscription fee.
104
So pick the app that you use the most,
105
and raise your hand if you would pay at least $5 a month.
106
OK, how about $10 a month?
107
20?
108
I don't see any hands anymore.
109
Well, let's do a quick calculation to figure out how much we're effectively paying for an app like TikTok.
110
We'll assume that you value your time at a rate of $20 per hour,
111
and you're spending two hours a day on the platform,
112
or 30 days in a month,
113
so you're effectively paying $1,200 per month for TikTok.
114
So when you start to do this kind of analysis,
115
it quickly becomes clear that most of us are drastically overpaying for social media.
116
My ask of you is this.
117
Figure out what it means for you to get a good deal out of social media platforms.
118
In order to do that,
119
you have to do two things.
120
You have to ask yourself,
121
what value do these services provide?
122
And second, you have to ask,
123
how much of your time is that value worth?
124
Now, I want to be clear that I am not saying social media is without value.
125
It can be an incredibly powerful tool.
126
It can foster relationships.
127
It can introduce you to new ideas.
128
It can even spark social movements.
129
But we need to learn to use it in moderation.
130
Don't let yourself get to the age of 90,
131
only to look back on your life and realize that while you were trying to avoid FOMO,
132
you actually missed out on living.
133
That free time is your most valuable resource.
134
Do not give it away for free.
135
Thank you.
136
Thank you.

この単語では強調される音節に焦点を当てることがポイントです。
これらを効果的に練習することで、スムーズな会話が可能になり、英語のスピーキング能力が向上します。
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。
