To know oneself, one should assert oneself.

You never know what motivates you.

Well done is better than well said.

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

Be kind whenever possible. It is always possible.

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

The dog that trots about finds a bone.

Be gentle to all and stern with yourself.

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