First principles thinking is the closest thing to a cheat code for life.

Successful people from Elon Musk all the way to Kobe Bryant used it to break conventions and become one of a kind.

First principles make you stand apart.

I got to use it too, from MIT all the way to billion dollar boardrooms.

If you're not careful, AI will make your thinking more average.

So I'll show you a four -step framework to think so clearly that people who you meet walk away thinking,

you must be some kind of a genius.

Let's get started.

For most of my last 12 years, I slept for less than four, five, six hours a night.

I was the CEO of one of the top 20 fastest growing companies in the US.

I worked at a large public company where we were growing like crazy.

And I traveled nonstop, worked past midnight.

So every single morning when I woke up, I would always feel totally exhausted from the first minute.

And I would load up on coffee and I would be ready for the day.

Then about three years ago, I retired from full -time operator executive work.

And my schedule obviously changed dramatically.

I had more control over my day.

I was on boards, I was advising, I was investing, but it wasn't 7 a .m till midnight every single day.

But still, every morning, I would wake up completely exhausted.

That was strange.

So I reached out to a great pulmonologist and sleep specialist, and they did a sleep study on me,

where they put me in a lab and measured how I slept

and what happened in my brain the medical data completely blew my mind.

The results showed that I was waking up 34 times an hour, every hour, all through the night.

The structure of my jaw is such that it was blocking my airway.

Now, I had no idea.

I had spent years trying to normalize the problem by telling myself, oh, I need more sleep or I have to go through this.

It's the grind.

I need more coffee.

I need to work less.

The moment I stopped perpetuating the story and deconstructed the system from first principles up, that fixed the root cause.

And I realized the problem was not where I thought it was.

That process of thinking is called the first principles thinking.

We're going to build a four -step framework here

and learn how to use AI to drive that process and how to build specific prompts for each of those steps.

So it's a bit dense.

So I'll make a PDF as well.

So you can see all of it in one place.

Link is in the description.

Of course, it's free.

We never investigate our own assumptions.

We inherit them from our colleagues, our families, industries, experts, or our own previous experiences.

First principles want you to begin somewhere else.

What do I actually know for sure?

What am I assuming?

What else could produce this result?

Which part can I test?

Imagine buying a car, driving it once, and then throwing it away.

That would sound insane, right?

But for decades, that was how most rockets worked.

Now, of course, rockets are not cars.

The physics is far more unforgiving.

Obviously, it's called rocket science for a reason.

But Elon Musk questioned the very assumption.

Why couldn't the rocket land vertically and fly again?

That question changed the economics of space travel.

So how do you start thinking in terms of first principles?

Maybe a couple of examples.

Maybe you're thinking, I can't focus.

Well, start digging in.

Is it focus or sleep or phone addiction or unclear tasks?

Too many priorities?

You're bored?

There's no deadline?

Or are you doing work with no real impact?

What is it?

Things are about to get worse because AI is here.

Let's go there next.

Consider how large language models actually work.

They do not physically observe the universe we're in.

They don't have the idea of reality, at least not yet.

And they don't have the real world experience.

They're mathematical models that are very good at matching patterns.

So when we ask a question, it looks for the most likely thing that matches the pattern.

The most familiar answer seems like the best answer.

That's the way AI is designed.

And the better AI sounds, the less you will check.

A general purpose AI model does not naturally start from first principles.

That's why you have to force AI to think differently.

That's the four -part framework.

We'll walk through each step and we will also construct prompts for each step.

So let's go to the first step, which is D for decompose.

Let's say if you want to start a business or even something simpler.

Let's say you want to start a YouTube channel.

If you talk to the experts and say, hey, I want to start a YouTube channel.

What do I need?

What are they going to say?

They'll say, oh, well, you need a studio.

You need a professional camera, good lighting.

You need an editor you need a creative director, a production agency.

And sure, if you can afford all of that,

those things may save you some time and improve the final product so you can focus on content creation.

But that's all conventional wisdom.

What if you boiled it down to its essential components?

Decomposed it.

What do you really need?

Just two things, a phone and a story.

You can start tomorrow.

You can start tonight.

100

The same idea applies to starting a company.

101

You can raise millions from some investors.

102

You can rent a swanky office in New York City.

103

But there are thousands of successful companies that got started without any of that.

104

So this step of decomposing is really about seeing the parts of the machinery.

105

This is where AI is going to be tremendously useful.

106

But remember that these models are also trained to be very eager and very helpful.

107

So the moment they see a problem, they would want to solve it.

108

You don't want that.

109

You want them to break the problem down into its essential parts.

110

Let's apply our friendly framework, AIM, to create a prompt.

111

I've covered the idea of AIM in this video before somewhere.

112

But if you haven't seen it, AIM stands for Actor, Input, Mission.

113

Tell the model who it's acting as, give it the context or data it needs, and then tell it what done looks like.

114

So here's the prompt.

115

Act as a world -class first principles analyst.

116

Your job in this step is decomposition only only.

117

You are penalized for introducing advice, solutions, assumptions, or standard playbooks.

118

Be my thought partner.

119

Do not suck up to me.

120

Intention.

121

I want to understand exactly what this problem is made up of.

122

My problem is, and then you will insert your problem, if the stated problem appears to contain a hidden or a deeper question,

123

identify it in one sentence before decomposing the current problem.

124

Ask whether I want you to decompose the original problem or the deeper one.

125

Do not continue until I choose.

126

Do not replace or reframe my problem until I tell you.

127

So you see, you're trying to constrain what AI needs to focus on.

128

And the third part is mission.

129

Break the problem into its smallest useful constituent parts.

130

Show the hierarchy clearly, the overall problem, its major components, and the smaller elements inside or under each component.

131

Use only dimensions that are relevant, such as people, process steps,

132

time, resources, costs, etc. For each component,

133

briefly explain what it contains and how it connects to the larger problem.

134

Stop decomposing when going down further would no longer improve my understanding.

135

Do not evaluate the components.

136

Do not recommend solutions.

137

Only show me what parts the problem is made up of.

138

So that was your first prompt.

139

And I'm sorry if it was a bit long or complicated,

140

but I'm hoping that it will give you clarity on how to boil down any problem into its essential parts.

141

That's part of the first principles thinking.

142

And also how to make sure that AI remains focused on the task that you give it.

143

Now, let's go to step two, where we look at each of these parts and see whether it's a fact or an assumption.

144

The most important first principle skill is auditing the assumptions.

145

After the second world war,

146

American car companies had enormous factories that produced big American cars for the big American market.

147

Now, Toyota was a very small company and they were based in Japan and we're talking about after

148

World War II.

149

So Japan was recovering, much less capital, fewer resources, and a much smaller market.

150

So copying Detroit would not have worked for Toyota.

151

Toyota couldn't have afforded it.

152

So they audited the assumptions underneath the idea of mass production itself.

153

Why make big cars?

154

Why not small cars?

155

Why produce them in huge batches?

156

Why do you need to hold such a large inventory?

157

What do you do when there is a defect?

158

Are there different better ways to organize the processes and people?

159

That thinking became the foundation of just -in -time production

160

and something that became so dramatically successful that American companies started implementing that.

161

And over time, Toyota overtook GM to become the world's largest automaker.

162

And, you know, years later, I feel like history is repeating itself because then came

163

Tesla that questioned the assumptions made by Toyota in all car makers.

164

Because Tesla asked, why do you even need a combustion engine at all?

165

And by 2020, Tesla had overtaken

166

Toyota as the world's most valuable automaker.

167

Most conventions that we cling to are just assumptions that have survived.

168

But true innovation requires that you break the rule, that you ignore the conventions.

169

And here's where AI can be a very valuable partner.

170

You can use the model to perform that audit that we're talking about.

171

Here's the prompt to do that.

172

And I'll just read the first part of the prompt and then we'll just put the entire prompt on the screen.

173

You can pause and take a screenshot or come back to it anytime you want.

174

And of course, all of this is going to be in a nicely formatted PDF.

175

You can get it for free.

176

Alright, here's the prompt.

177

Act as a skeptical red team analyst,

178

whose only job is to uncover and question inherited assumptions.

179

Assume that every obvious part of the problem may be hiding a convention until evidence proves otherwise.

180

Intention, I want to know which of the building blocks above are assumptions

181

And so on So this is the entire prompt

182

Now, once you identify the assumption

183

You may feel like you may have destroyed the entire solution that you were thinking about And that's a good thing

184

Because now you finally have the freedom to build a better solution from the ground up

185

And for that, we go to the next step, which is R for recombining.

186

I think music gives us the simplest way to understand the idea of recombination.

187

Most modern Western music is built from 12 notes.

188

If you're trained in Western music, that's your alphabet.

189

You don't spend your entire life searching for a secret 13th note.

190

But if you came from, let's say, Indian classical music tradition, I came from there, or Arabic music,

191

they would use pitches that fall between the 12 notes of a Western piano.

192

So if you only listen to, let's say, American pop all your life, and you suddenly hear Arabic music,

193

it may sound to you as if it's out of tune, at first at least.

194

But it's not.

195

It's just that your ear is set to a different set of rules, the power of convention.

196

But even with those 12 notes, You can recombine them into millions and millions of songs and compositions.

197

Bach used them very differently than the Beatles.

198

And Beatles used them very differently than Beyonce.

199

They all used the same 12 notes to create different magic.

200

Same ingredients, millions of dishes.

201

That's where recombination comes into play.

202

Innovation is not about looking for that secret 13th note.

203

You just need the right combination of the 12 nodes that you already have.

204

AI is unusually powerful here because it can search millions of combinations at a scale no human being can.

205

Here's the R prompt.

206

I'm just going to put it on the screen.

207

And of course, there is a PDF link.

208

Here's the actor, the intention.

209

Here's the mission.

210

Now, you have a handful of possibilities.

211

There are ways to combine these ideas but they're still all theoretical.

212

The final step is where the practical world gets to vote.

213

That's our fourth step, E, for experiment.

214

You know, James Dyson, who was an inventor, noticed that these vacuum cleaners lost suction as their bags filled with dust.

215

And it took him 5 ,127 prototypes over five years before he could reach his breakthrough design.

216

And it's the same reason Google used to run millions of

217

experiments on what exact shade of blue color would encourage people to click on links.

218

The first principle thinking is hard.

219

It is counterintuitive, but it's still a clean process until the fourth step.

220

The real world experiments are inherently messy.

221

They're hard, they're risky, and they have real consequences if you fail.

222

That's why AI can be a very good simulator.

223

You can use AI to design these experiments for you.

224

Here's a prompt for it.

225

Here's the actor.

226

Act as a skeptical scientist.

227

Your job is to help me design the cheapest,

228

fastest way to find out whether this holds up before it costs me anything real in time,

229

money, effort, reputation.

230

Don't try to sell me the idea.

231

Give me the test I could actually run.

232

So that's the actor.

233

Here's the intention.

234

Here's the mission.

235

And notice what it says at the bottom of the mission part of the prompt.

236

And I like it a lot.

237

For each test, tell me what result would rule that solution out

238

and what result would keep it alive and what I'd learn from the problem either way.

239

Give me your view on which building block to revisit if all the tests fail.

240

And the reason I like it is

241

because the whole point of first principles thinking is to keep us learning about where our failures

242

and successes are and what they're caused by.

243

So, yay, we made it.

244

It was a bit dense, but that was there.

245

And it's yours.

246

Make it better.

247

Share it with others.

248

Make sure every prompt makes the machine show its work to you.

249

And by the way, make sure that you are the decision maker.

250

AI does the work.

251

AI shows you the work.

252

You keep the judgment.

253

Now, one point I would make about first principles and the framework,

254

they won't give you a surefire way to avoid failure.

255

The goal is not to be right every time.

256

It is to learn quickly why you are wrong.

257

Martin Short has been one of the most talented comedic actors for, I don't know, more than 40 years.

258

And yet, most of his movies have flopped.

259

But he's still one of the most successful comedians in North America today.

260

And he was talking to a young comedian.

261

He gave him a wonderful advice.

262

He said, in this business, you fail 98 % of the time.

263

Those are great odds.

264

I love that line.

265

Most of what I have tried in my life didn't work either.

266

My failure rate is right around there.

267

You know, yours might be too.

268

But even if you have such a terrible hit rate as mine,

269

the math eventually still works out in your favor.

270

Because when you find just that 2 % that actually works,

271

it can change the entire trajectory of your life.

272

You don't need 100 wins.

273

You only need one.

274

Thank you, and I love you.

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。
