What you do today can improve all your tomorrows.
Wherever you are - be all there.
Quality is not an act, it is a habit.
The secret of getting ahead is getting started.
Well done is better than well said.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
Begin to be now what you will be hereafter.
If you can dream it, you can do it.
If you're going through hell, keep going.
Nuclear arms and atomic power represent a technology in which coexistence with man is extremely difficult.
