The secret of getting ahead is getting started.
Only the educated are free.
You never know what motivates you.
Go for it now. The future is promised to no one.
Without hard work, nothing grows but weeds.
If you think you can do it, you can.
What you do today can improve all your tomorrows.
Expect problems and eat them for breakfast.
To be a good loser is to learn how to win.
Quality is not an act, it is a habit.
I wrote somewhere during the Cold War that I sometimes wish the Iron Curtain were much taller than it is, so that you could see whether the development of science with no communication was parallel on the two sides. In this case it certainly wasn't.
