Know or listen to those who know.

It's always too early to quit.

Go for it now. The future is promised to no one.

Be thine own palace, or the world's thy jail.

Well done is better than well said.

To be a good loser is to learn how to win.

Either you run the day or the day runs you.

By failing to prepare, you are preparing to fail.

Expect problems and eat them for breakfast.
