Sometimes I know things. Occasionally, I surprise people with my random knowledge of trivial things. Sometimes, even surprise myself.

But most of the time, I don’t know — most of us don’t — about anything.

Acknowledging this, admitting this, is how you learn.

The problem is that our ego makes this admission difficult. We don’t like not knowing, even when we don’t.

The sooner you stop pretending always to have an answer, the smarter you’ll become. When you start saying “I don’t know,” you open yourself up to learning.
