Do not weep do not wax indignant. Understand.
Be thine own palace, or the world's thy jail.
Problems are not stop signs, they are guidelines.
After a storm comes a calm.
Either you run the day or the day runs you.
Know or listen to those who know.
The wise does at once what the fool does at last.
Things do not happen. Things are made to happen.
You never know what motivates you.
If you're going through hell, keep going.
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.
