Without hard work, nothing grows but weeds.

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

It's always too early to quit.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

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

The secret of getting ahead is getting started.

Leap, and the net will appear.

I can, therefore I am.
