Let him who would enjoy a good future waste none of his present.

Experience has taught me that there is one chief reason why some people succeed and others fail. The difference is not one of knowing, but of doing. The successful man is not so superior in ability as in action. So far as success can be reduced to a formula, it consists of this: doing what you know you should do.

Lose not yourself in a far off time, seize the moment that is thine.
