Didn't we already have this discussion a while back?
I think anyone can be a great artist (well maybe not people who have some sort of handicap that doesn't make it possible to practice) if they really really want it and work for it.
I think that you just need to practice a lót, and it's good to have people around who can really criticize your work so you know what not to do so you can improve quicker (CA is a good place for that ).
So I think that if you're passionate about something, and willing to practice a lot, not much will hold you back from getting to be good at it.
I think he more meant that everyone can draw but not everyone can be the -best-. There's a certain combination of understanding, experience and circumstance that goes into these things, yeah? But everyone is capable of learning to draw and doing it well. It is really all about practice, and also observation. The better you train yourself to observe the visual world around you, the better you'll be able to put things on paper, whether they're from life or from your head. I'd definitely take a look at what Marko said about drawing...in that...thread. Lemme snatch a link.
There are two primary tools involved...your hands and your head. Anybody can learn to use the first to learn how to draw quite well. Not that many can get the second tool working right, so not everybody can do something truly creative that stands out from the crowd.
