Be gentle to all and stern with yourself.
To be a good loser is to learn how to win.
Leap, and the net will appear.
The most effective way to do it, is to do it.
You never know what motivates you.
The wise does at once what the fool does at last.
Never complain and never explain.
Expect problems and eat them for breakfast.
Be thine own palace, or the world's thy jail.
Who seeks shall find.
Science is a self-sufficient activity.
The thing about science is that it's an accurate picture of the world.
