It's kind of an arbitrary, I don't remember if he says 300 or not, but there's some number of limited quantity of domains and that in each of these, there are two or three big ideas that carry all the 80% of the freight, as he said it.

And so if you were to go and learn those two or three big ideas from each of the disciplines up your alley, I'm sure you've written about this before.

You have all these mental models and you have lots of stuff to hang things on.

And then also a lot of the innovation in the world comes from taking an idea from one domain and applying it elsewhere, a mental model from one applying it elsewhere.

So I learned about this when I was like 25 or so living in China.

And that really set me off on learning.

a lifetime journey of like trying to read because like learn as many of these domains as I could, you try to be worldly wise.

Um, and so I, I, I love that.

It really inspired me.

And then one day I was at a party at a house in Silicon Valley, not like a fun party, but like, you know, gathering a cocktail event or something.

And, um,

I didn't know anybody.

And I, this older guys, older gentleman was there and I struck up, he struck up a conversation.

He saw me not talking to anyone or something.

We started talking to each other.

And he, at some point asked me what my favorite book was.

I told him it's, it's poor Charlie's almanac.

And because he's like, why do you like that book?

And I told him all this and he's like, well, I know that book really well, actually.

I'm the author of that book.
