If you can dream it, you can do it.
Be gentle to all and stern with yourself.
Be kind whenever possible. It is always possible.
Quality is not an act, it is a habit.
Always desire to learn something useful.
Things do not happen. Things are made to happen.
You never know what motivates you.
Problems are not stop signs, they are guidelines.
If you've got a talent, protect it.
The secret of getting ahead is getting started.
Triumphant science and technology are only at the threshold of man's command over sources of energy so stupendous that, if used for military purposes, they can wipe out our entire civilization.
