If you want to think more clearly than 99% of people,

learn more quickly, and master almost anything in the age of AI,

you need to bring back one forgotten skill.

How to think on paper.

I've spent decades in boardrooms and tech companies worth billions,

and the sharpest thinkers I know still reach for pen and paper.

So in this video, I'm going to share a complete system for how to think,

how to learn, how to create using the most powerful thinking tool you already own.

One that costs you a dollar.

Sure, paper will not replace your keyboard or AI today,

but it can make you much harder to replace.

So let's get started.

The first thing we want to talk about is why pen is mightier than the prompt.

Writing is slower than typing.

Typing slower than prompting.

But But with each step,

we hand off one more layer of our thinking to a machine.

We humans have been thinking with our hands for thousands of years.

There is a university in Norway,

NTNU, and the scientists there found that when we write on paper,

the parts of our brain that light up are the same parts where ideas,

memories, and learning take place.

But the world we live in today is very different.

We prompt more than we produce.

We used to shape ideas on paper.

Now we just rent them,

we select them from whatever the machine throws at us.

As the French philosopher Descartes once said,

I think, therefore I am.

Well if you outsource your thinking, what's left of you?

Here's what surprised me the most.

Writing on paper literally shapes your thoughts.

That's why the top leaders still think on paper.

For instance, Da Vinci kept 7,000 pages of handwritten books.

Drawings, diagrams, sketches, blueprints, whatever he could get his hands on.

Charles Darwin worked out the theory of evolution by drawing diagrams.

And sure, you would say,

well, computers weren't invented then,

so they had to write on paper.

But the same applies for business leaders and thinkers today.

From Richard Branson to Nobel Prize winning author Toni Morrison,

and from Michelle Obama to Sam Altman,

their ideas start on a piece of paper.

And here's the surprise.

On paper, you're not just writing, you're drawing by hand.

And our brain treats it very differently than just typing.

When you type, every keystroke is the same motion.

of your fingers pressing down A or Z,

love letter or legal brief.

The physical act of creating each letter is identical,

which is great for speed.

But when you write by hand,

every letter is a unique physical experience.

The pressure of the pen,

the speed of the stroke,

the curve of each shape.

In neuroscience, this is called haptic perception.

Your brain tags each idea with a sensory fingerprint.

The thought does not just live on paper,

it lives in your body.

Every letter you write gives shape to your thoughts.

Current science shows that even doodling seems to lower cortisol and reduce performance anxiety.

And here's my favorite example.

J.K.

Rowling wrote the first chapters of Harry Potter by hand in a cafe in Edinburgh while she was surviving on government benefits,

anxious about her future.

A single mother, single pen,

a piece of paper, 450 million copies sold.

Now, of course, not everything belongs on paper.

But once you know when to use paper,

it changes is how you think,

how you create, and how you even feel.

Here's the framework I call the three originals.

The first one is invention.

What do you do when you need to generate something that doesn't exist in the world yet?

A new idea, a solution, a direction, a strategy?

Use paper to write whatever comes to mind.

The rule here is simple.

Create.

Don't criticize.

While you're regenerating, tell your internal judge to take a vacation.

Be free, be messy, write whatever comes to mind,

fragments, flashes of completely unrelated thoughts, doodles, drawings.

You want to give your brain some breathing room

so it can fly through the white space and make connections it hasn't made before.

The second is introspection.

This is where the fog refuses to lift.

I remember when When I used to feel overwhelmed or defeated or angry or stuck,

I would use paper as my friend, my external mind.

It's hard to think your way out of any emotional fog.

Sometimes though, you can give it a language.

Label your feelings.

Name them.

Accept them.

Navigate the inner maze.

Let the page carry the burden so you can feel light.

Once it's out, you can see it.

And once you can see it, you can move.

And by the way, sometimes typing feverishly also works for me because it captures the stream of consciousness.

100

But usually I find the slower process of writing on paper produces much deeper catharsis.

101

And the third is intuition.

102

Einstein reportedly said if he had one hour to solve a problem,

103

he would spend 55 minutes defining it and five minutes solving it.

104

That's first principle thinking.

105

Untangling the problem itself.

106

What do I actually know to be true?

107

What am I assuming?

108

How do I formulate this problem?

109

That's where paper comes handy.

110

So invention, introspection, and intuition.

111

Now why do I call them three originals?

112

Because they are the three unique traits that make you and me truly human.

113

No other human or machine can do those three steps exactly the same way that you'll do them.

114

They are like your fingerprints.

115

Now let's talk about staring down the void.

116

Because maybe you're thinking, alright this sounds right,

117

but the moment I face a blank page, I always freeze.

118

Does this happen to you?

119

Researchers from Princeton and UCLA found that students who took notes by hand understood concepts more deeply than those who typed.

120

Now the typists recorded more words but they they ended up understanding less.

121

More speed with less depth.

122

So if the evidence is this clear,

123

why don't we use paper all the time?

124

Because we don't like staring at the blank page.

125

You know the blank page syndrome is exactly what drives all of us to chat GPT.

126

Type something, anything, and within three seconds,

127

you're gonna get three paragraphs.

128

Instant relief, but only to the symptom.

129

The underlying cause never gets addressed.

130

Because if you shy away from the most uncomfortable moment in all of creative and intellectual work,

131

that blank page, then you're shying away from clarity and originality.

132

In psychology, it's called desired difficulty.

133

The harder your brain has to work to generate a thought,

134

the deeper gets wired in.

135

The strong resistance is what gives rise to strong results.

136

But doing it without judgment is hard.

137

Here's what happens to all of us.

138

A friend of mine is one of the best cooks I know.

139

Cooking is her calling.

140

She loses herself in it and every dish is a masterclass.

141

But then there are weeks where she just hates cooking.

142

I asked her about it and she said,

143

that's when my mother-in-law is visiting and she stands right there next to me in the kitchen.

144

So no matter how good you are at what you do,

145

when you have to do it while being judged,

146

there's no chance you're gonna create your masterpiece.

147

So I think the blank page is not our problem.

148

The real problem is our inner judge that's staring at it.

149

And that inner voice is telling you that you have nothing new to say.

150

Well, don't listen to it.

151

When you sit down in front of that blank page,

152

you want to quickly form precise ideas.

153

Those four words are your four judges.

154

Quickly form precise ideas.

155

Let's take each one.

156

First, quickly.

157

Why rush?

158

What's the rush?

159

Your best thinking never arrives on schedule.

160

So give it 15 minutes,

161

maybe 20 minutes, stare at it for a while.

162

The point of the paper is to slow you down.

163

Quickly is overrated.

164

Second, form.

165

Nothing on this page needs to be well-formed.

166

Half a thought, good.

167

Disconnected words, great.

168

An arrow pointing nowhere, even better.

169

All of it counts.

170

No one's gonna see this piece of paper but you.

171

Third, precise.

172

Now this is the biggest trap for a lot of us.

173

Be random, be imprecise, let it flow.

174

Even if you haven't found any words yet, write them anyway.

175

And fourth, ideas.

176

It does not have to be a great idea,

177

or a new idea, or even an idea.

178

It can be a feeling,

179

a question, a word, a phrase, a doodle, a shape.

180

Whatever shows up in your head is yours.

181

So go ahead and fire all those four judges.

182

And remember, you don't need to fill that page.

183

You just have to empty your mind.

184

Do that honestly enough, and that blank page will take care of itself.

185

You know, every idea has a journey,

186

and it needs many vehicles, paper, keyboard, and AI.

187

They're not rivals.

188

They're partners.

189

You just need to build a system to integrate them.

190

The core question behind this system is not about which tool is best.

191

It's what your idea needs next.

192

So there are three ways to think about it.

193

First, if your idea needs freedom, go to paper.

194

When the idea is still fragile,

195

you know, it's a feeling,

196

a fragment, a question that won't leave you alone.

197

Still in its embryonic stage,

198

it needs time and space to be born.

199

That's where paper is perfect.

200

Because on paper, you can let it breathe.

201

Because there's no cursor blinking at you and waiting for you.

202

No auto-complete.

203

No undo.

204

Just you and your freedom.

205

Second, if your idea needs form, go to the keyboard.

206

Because you're at a point now when your idea has a pulse.

207

And it needs structure and some kind of sequence, sentences.

208

but you still want to spend time with it.

209

You want to be alone with it.

210

That's where keyboard is very good.

211

And finally, if the idea needs feedback,

212

then go to AI by all means.

213

It's your collaborator and your co-pilot.

214

You can have a dialogue with it.

215

It can challenge your idea.

216

It can expand it.

217

It can pressure test it.

218

It can recombine it.

219

Find what's missing.

220

This is where deep research is a great tool.

221

Now, this framework is not a sequence.

222

So you can interchange keyboard and AI in any order of your choice.

223

It all depends on what your idea needs next.

224

For example, this video started on this paper,

225

30 minutes away from any screen.

226

Just fragments, arrows, questions I couldn't answer yet.

227

Then I went to the keyboard for structure.

228

Then AI for deep research and refinement.

229

Then back again on paper.

230

when I got stuck, I doodled on paper, went for a walk.

231

So from paper to keyboard to AI to paper,

232

you know, the loop continued.

233

Your system is based on what you need next.

234

Is it freedom?

235

Is it form?

236

Is it feedback?

237

Your vehicle will change on this journey accordingly.

238

But in the end, the journey starts with you and ends with you.

239

And that's the most important takeaway from all of this.

240

AI can amplify your ideas,

241

expand them, polish them, even execute your ideas at a scale you never imagined.

242

But it cannot create them for you.

243

For that, it's you and that piece of paper.

244

Today, AI is already smarter than us in many ways.

245

And intelligence is becoming cheap.

246

It's becoming a commodity.

247

So what makes you irreducibly human?

248

your creation, your emotion, your intuition.

249

You know, the three originals.

250

And paper protects all three of them.

251

Think of a sculptor.

252

They don't begin with polish.

253

First comes the rough shape,

254

you know, the messy first cuts,

255

all that work that nobody sees.

256

And if you polish too early,

257

you will ruin the sculpture.

258

That's why thinking on paper is so crucial.

259

Because, you know, From the beginning of human progress,

260

every giant leap began as a small, innocent, original idea.

261

But each one of them was forged in solitude through messy first cuts.

262

Your ideas are the same.

263

When you shape them in solitude,

264

they shape who you become and they shape the world around you.

265

So make your first cut.

266

Make it yourself on a piece of paper before the world or the machine gets to reshape it for you.

267

Because it's the most human thing you can do.

268

If you like this video,

269

here's the latest one on how you can have many interests and still be amazingly successful.

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。
