Be kind whenever possible. It is always possible.
Be gentle to all and stern with yourself.
If you've got a talent, protect it.
Quality is not an act, it is a habit.
You never know what motivates you.
Be thine own palace, or the world's thy jail.
Well done is better than well said.
After a storm comes a calm.
Either you run the day or the day runs you.
Know or listen to those who know.
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.
