Waiting for four years might sound kind of bad at first, but you have to keep in mind that it takes about 5-10 years for an artist to become established in the art world (and this is AFTER they're at a professional level). Simply put - art is a slow, slow field that takes a bunch of time and effort to get into.

Not sure if you saw my other comment, but Noah talks specifically about your question at ~23:30 minutes in.
