Nothing is done. Everything in the world remains to be done or done over. The greatest picture is not yet painted, the greatest play isn’t written, the greatest poem is unsung.
-Lincoln Steffens, 1931
If you truly believe this, then your best work will be forced to always be ahead of you. And you'll be forced to realize that there a lot of creative people that have come before you, are here now, and will be here after you. None of them are or ever will be perfect.
This is a good thing.
Now. How bout them Giants?
