Be thine own palace, or the world's thy jail.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
Know or listen to those who know.
I can, therefore I am.
If you've got a talent, protect it.
Be kind whenever possible. It is always possible.
If you're going through hell, keep going.
You never know what motivates you.
Expect problems and eat them for breakfast.
Science is a differential equation. Religion is a boundary condition.
