It's always too early to quit.

You never know what motivates you.

If you're going through hell, keep going.

If you can dream it, you can do it.

If you think you can do it, you can.

The secret of getting ahead is getting started.

Know or listen to those who know.

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

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