Things do not happen. Things are made to happen.
Who seeks shall find.
Without hard work, nothing grows but weeds.
Be gentle to all and stern with yourself.
Begin to be now what you will be hereafter.
Well done is better than well said.
Wherever you are - be all there.
After a storm comes a calm.
Leap, and the net will appear.
If you think you can do it, you can.
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.
