"Someone once asked me what I regarded as the three most important requirements for happiness. My answer was: “A feeling that you have been honest with yourself and those around you; a feeling that you have done the best you could both in your personal life and in your work; and the ability to love others."
"In order to be utterly happy the only thing necessary is to refrain from comparing this moment with other moments in the past, which I often did not fully enjoy because I was comparing them with other moments of the future."
