It's always too early to quit.
The dog that trots about finds a bone.
What you do today can improve all your tomorrows.
If you've got a talent, protect it.
To be a good loser is to learn how to win.
Either you run the day or the day runs you.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
Never complain and never explain.
To know oneself, one should assert oneself.
Success breeds success, and failure leads to a sort of fallow period.
