It's always too early to quit.

Be thine own palace, or the world's thy jail.

If you've got a talent, protect it.

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

Without hard work, nothing grows but weeds.

Leap, and the net will appear.

Know or listen to those who know.

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

The secret of getting ahead is getting started.
