Wherever you are - be all there.
Begin to be now what you will be hereafter.
Either you run the day or the day runs you.
Go for it now. The future is promised to no one.
Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
I can, therefore I am.
Only the educated are free.
Things do not happen. Things are made to happen.
The wise does at once what the fool does at last.
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.
