Better to do a little well, then a great deal badly.

Socrates

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

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

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

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

A multitude of books distracts the mind.

We are what we repeatedly do. Excellence then is a habit.
