I can, therefore I am.

Things do not happen. Things are made to happen.

Either you run the day or the day runs you.

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

Well done is better than well said.

Expect problems and eat them for breakfast.

If you can dream it, you can do it.

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

Know or listen to those who know.
