To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

Without hard work, nothing grows but weeds.

If you think you can do it, you can.

The secret of getting ahead is getting started.

It's always too early to quit.

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

Be gentle to all and stern with yourself.

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