To know oneself, one should assert oneself.

Never complain and never explain.

Be kind whenever possible. It is always possible.

Be gentle to all and stern with yourself.

If you've got a talent, protect it.

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

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

The secret of getting ahead is getting started.

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