To know oneself, one should assert oneself.

The dog that trots about finds a bone.

What you do today can improve all your tomorrows.

It's always too early to quit.

Only the educated are free.

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

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

Either you run the day or the day runs you.

I can, therefore I am.
