Be gentle to all and stern with yourself.

I can, therefore I am.

Things do not happen. Things are made to happen.

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

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

To know oneself, one should assert oneself.

Problems are not stop signs, they are guidelines.

It's always too early to quit.

If you've got a talent, protect it.
