Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great.

It is not enough to aim; you must hit.

First say to yourself what you would be; and then do what you have to do.

If you refuse to be made straight when you are green, you will not be made straight when you are dry.

We must learn to be still in the midst of activity and to be vibrantly alive in repose.

Any sufficiently advanced bureaucracy is indistinguishable from molasses.

Make up your mind to act decidedly and take the consequences. No good is ever done in this world by hesitation.

Having once decided to achieve a certain task, achieve it at all costs of tedium and distaste. The gain in self-confidence of having accomplished a tiresome labor is immense.

For the things we have to learn before we can do them, we learn by doing them.

To find a fault is easy; to do better may be difficult.
