Be gentle to all and stern with yourself.
Only the educated are free.
Either you run the day or the day runs you.
If you've got a talent, protect it.
Begin to be now what you will be hereafter.
The most effective way to do it, is to do it.
Expect problems and eat them for breakfast.
Wherever you are - be all there.
Go for it now. The future is promised to no one.
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.
