"Why fret too much about what you can't fix? Just keep your head down & do your best." - Charlie Munger

The first helpful notion is that it is usually best to simplify problems by deciding big no-brainer questions first. The second helpful notion mimics Galileo’s50 conclusion that scientific reality is often revealed only by math as if math was the language of God.

It’s not given to human beings to have such talent that they can just know everything about everything all the time. But it is given to human beings who work hard at it — who look and sift the world for a mispriced bet — that they can occasionally find one. And the wise ones bet heavily when the world offers them that opportunity. They bet big when they have the odds. And the rest of the time, they don’t. It’s just that simple.

In my whole life, I have known no wise people (over a broad subject matter area) who didn't read all the time — none, zero. You'd be amazed at how much Warren reads — and at how much I read. My children laugh at me. They think I'm a book with a couple of legs sticking out.
