If you're going through hell, keep going.
Things do not happen. Things are made to happen.
Never complain and never explain.
Well done is better than well said.
Always desire to learn something useful.
If you've got a talent, protect it.
After a storm comes a calm.
If you can dream it, you can do it.
Expect problems and eat them for breakfast.
Be gentle to all and stern with yourself.
Science is a differential equation. Religion is a boundary condition.
