KISS

Keep it Simple Stupid

"The other day I was dealing with a problem and I said, this thing has 3 things I've learned to fear: an architect, a contractor and a hill." https://x.com/Giuliano_Mana/status/1993426664534229341

Some things are intrinsically difficult.

And you can't just outsource your thinking.

"We'd rather multiply by 3 than by π"

It's easier that way.

Whenever possible, Warren stays away from complexity. Why going for π if you can go for 3.

“I don't look to jump over 7-foot bars. I look around for 1-foot bars that I can step over.”

No extra reward comes from complexity. You might get some admiration from non-knowers, but that's about it.

All things equal, the simplest explanation is the best one. Easiest to remember and recall. Easiest to practice.

There's much more power in simple ideas than in complicated ones. They can scale and are repeatable. Mastery comes from doing the same simple thing over and over again.

But don't force simplicity. It must be 'as simple as possible, but not simpler'.

To test for this:

1. Use Feynman's question: Can you teach it to a 5-year old?

2. Use Darwin's guiding principle: Is it true?
