It's always too early to quit.

You never know what motivates you.

If you're going through hell, keep going.

Quality is not an act, it is a habit.

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

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

After a storm comes a calm.

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

Expect problems and eat them for breakfast.
