Chuck Close is an incredible portrait artist who is a huge inspiration... you might have to go to the fora.tv site to see the whole thing. its like an hour long. but if u just wanna skip to certain parts it has titled chapters on the fora.tv site. The part about disabilities is pretty great. Kind of makes you feel like an A-hole for ever making excuses for not doing something though...
If your an artist you should probably watch/listen to it all the way through tho.
