I can, therefore I am.

Be gentle to all and stern with yourself.

If you've got a talent, protect it.

The wise does at once what the fool does at last.

Quality is not an act, it is a habit.

Go for it now. The future is promised to no one.

The secret of getting ahead is getting started.

To know oneself, one should assert oneself.

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