What you do today can improve all your tomorrows.

To know oneself, one should assert oneself.

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

I can, therefore I am.

If you're going through hell, keep going.

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

Always desire to learn something useful.

You never know what motivates you.

The dog that trots about finds a bone.
