It's always too early to quit.
If you've got a talent, protect it.
The wise does at once what the fool does at last.
Wherever you are - be all there.
Only the educated are free.
If you think you can do it, you can.
The most effective way to do it, is to do it.
Be thine own palace, or the world's thy jail.
Never complain and never explain.
To be a good loser is to learn how to win.
The ballplayer who loses his head, who can't keep his cool, is worse than no ballplayer at all.
