I can, therefore I am.

You never know what motivates you.

The most effective way to do it, is to do it.

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

If you've got a talent, protect it.

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

The secret of getting ahead is getting started.

Things do not happen. Things are made to happen.
