Only the educated are free.
Either you run the day or the day runs you.
The dog that trots about finds a bone.
Know or listen to those who know.
By failing to prepare, you are preparing to fail.
After a storm comes a calm.
Well done is better than well said.
Without hard work, nothing grows but weeds.
The secret of getting ahead is getting started.
Be gentle to all and stern with yourself.
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.
