Every time you desire, or fear, or hate; every time you
boast or indulge your vanity; every time you struggle to get something for
yourself, you are really asserting: “I am a separate, unique individual, I
stand apart from everything else in this universe.” … Try to overcome this
possessive attitude towards your actions. Stop taking credit for your
successes. Stop bemoaning your failures, and making excuses for them. Stop
worrying so much about results. Just do the best you can. Work for work’s sake.
— The English author Christopher Isherwood, from a 1939 diary entry quoted in Isherwood by Peter Parker
