It's always too early to quit.

Without hard work, nothing grows but weeds.

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

If you've got a talent, protect it.

Know or listen to those who know.

Be kind whenever possible. It is always possible.

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

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

Expect problems and eat them for breakfast.
