Never complain and never explain.

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

Know or listen to those who know.

Either you run the day or the day runs you.

I can, therefore I am.

To know oneself, one should assert oneself.

The dog that trots about finds a bone.

By failing to prepare, you are preparing to fail.

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