The wise does at once what the fool does at last.
Who seeks shall find.
Be thine own palace, or the world's thy jail.
It's always too early to quit.
Things do not happen. Things are made to happen.
Well done is better than well said.
Be gentle to all and stern with yourself.
If you're going through hell, keep going.
Expect problems and eat them for breakfast.
Quality is not an act, it is a habit.
Because of my medical and ideological training, I am accustomed to saying that life is adaptation and symbiosis.
