What another would have done as well as you, do not do it. What another would have said as well as you, do not say it; what another would have written as well, do not write it. Be faithful to that which exists nowhere but in yourself - and thus make yourself indispensable.
Andre GideEverything has been said before, but since nobody listens we have to keep going back and beginning all over again.
Andre GideDo not do what someone else could do as well as you. Do not say, do not write what someone else could say, could write as well as you. Care for nothing in yourself but what you feel exists nowhere else. And, out of yourself create, impatiently or patiently, the most irreplaceable of beings.
