Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
Only the educated are free.
It's always too early to quit.
Well done is better than well said.
If you think you can do it, you can.
Who seeks shall find.
Go for it now. The future is promised to no one.
The secret of getting ahead is getting started.
Without hard work, nothing grows but weeds.
Nuclear arms and atomic power represent a technology in which coexistence with man is extremely difficult.
