If you've got a talent, protect it.
If you're going through hell, keep going.
I can, therefore I am.
Quality is not an act, it is a habit.
Expect problems and eat them for breakfast.
Always desire to learn something useful.
If you can dream it, you can do it.
The dog that trots about finds a bone.
Go for it now. The future is promised to no one.
Be gentle to all and stern with yourself.
That attitude does not exist so much today, but in those days there was a very sharp distinction between basic physics and applied physics. Columbia did not deal with applied physics.
