It is one of the beautiful compensations in this life that no one can sincerely try to help another without helping himself.
You will never be happy if you continue to search for what happiness consists of. You will never live if you are looking for the meaning of life.
Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.
Don't go around saying the world owes you a living. The world owes you nothing. It was here first.
