You need to get one thing done well, or else you don't have permission to do anything else.

The most important decisions you make are not the things you do, but the things you decide not to do.

Do not try to do everything. Do one thing well.

Don't get sidetracked. If you do get sidetracked, get back on track as soon as possible. Ultimately sidetracking kills you.

I know you won't believe me, but the highest form of Human Excellence is to question oneself and others.

There's no good answer to a question you didn't hear.
