Know or listen to those who know.

The secret of getting ahead is getting started.

Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

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

I can, therefore I am.

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

If you're going through hell, keep going.

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