It's always too early to quit.
To be a good loser is to learn how to win.
If you've got a talent, protect it.
Never complain and never explain.
Be thine own palace, or the world's thy jail.
Know or listen to those who know.
Do not weep do not wax indignant. Understand.
Who seeks shall find.
The secret of getting ahead is getting started.
Begin to be now what you will be hereafter.
Success seems to be connected with action. Successful people keep moving. They make mistakes, but they don't quit.
