It's always too early to quit.

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

Know or listen to those who know.

The most effective way to do it, is to do it.

Well done is better than well said.

If you've got a talent, protect it.

Do not weep do not wax indignant. Understand.

Be gentle to all and stern with yourself.

I can, therefore I am.
