The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
If you think you can do it, you can.
Go for it now. The future is promised to no one.
If you're going through hell, keep going.
Expect problems and eat them for breakfast.
Quality is not an act, it is a habit.
To know oneself, one should assert oneself.
Who seeks shall find.
After a storm comes a calm.
Beauty is the first test: there is no permanent place in the world for ugly mathematics.
