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

It's always too early to quit.

Be gentle to all and stern with yourself.

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

Always desire to learn something useful.

The dog that trots about finds a bone.

To know oneself, one should assert oneself.

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

If you're going through hell, keep going.
