To know oneself, one should assert oneself.

Know or listen to those who know.

After a storm comes a calm.

If you think you can do it, you can.

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

By failing to prepare, you are preparing to fail.

Expect problems and eat them for breakfast.

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

Either you run the day or the day runs you.
