To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.

If you've got a talent, protect it.

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

Never complain and never explain.

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

Things do not happen. Things are made to happen.

Well done is better than well said.

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