It's always too early to quit.
Never complain and never explain.
Things do not happen. Things are made to happen.
Be kind whenever possible. It is always possible.
To be a good loser is to learn how to win.
If you've got a talent, protect it.
Be thine own palace, or the world's thy jail.
Leap, and the net will appear.
The wise does at once what the fool does at last.
Either you run the day or the day runs you.
It is no use painting the foot of the tree white, the strength of the bark cries out from beneath the paint.
