By failing to prepare, you are preparing to fail.

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

If you've got a talent, protect it.

Never complain and never explain.

Know or listen to those who know.

If you're going through hell, keep going.

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

To know oneself, one should assert oneself.

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