Look for your own.

Look for your own. Do 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.          

– André Gide
