It's always too early to quit.

The dog that trots about finds a bone.

To know oneself, one should assert oneself.

If you've got a talent, protect it.

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

The wise does at once what the fool does at last.

What you do today can improve all your tomorrows.

If you think you can do it, you can.

Leap, and the net will appear.
