Always desire to learn something useful.
If you're going through hell, keep going.
I can, therefore I am.
Well done is better than well said.
The secret of getting ahead is getting started.
If you've got a talent, protect it.
Only the educated are free.
The most effective way to do it, is to do it.
Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
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.
