EDIT:
(Ignore the ANGER icon. Stupid Deviant Art won't let me change it for some reason. I guess I'm just typecast?)
Perfectionism is worse than a terminal disease to an artist.
With a terminal disease, an artist can complete a work of art, complain about what's wrong with it, die, and have the art sell for millions.
With perfectionism, an artist will ultimately finish nothing, complain about what he hasn't completed, die, and leave nothing behind.
Thoughts?
