If you can dream it, you can do it.
Never complain and never explain.
The dog that trots about finds a bone.
Know or listen to those who know.
The secret of getting ahead is getting started.
If you're going through hell, keep going.
After a storm comes a calm.
Leap, and the net will appear.
What you do today can improve all your tomorrows.
Well done is better than well said.
Beauty is the first test: there is no permanent place in the world for ugly mathematics.
