I agree with Davver.
I studied Graphic Design in an effort to someday become a full time illustrator / concept artist. It didn't help at all and I do regret wasting my time studying graphic design.
Davver also has a great point tho, you can have all the degrees in the world and still not be a successful artist, it takes a good portfolio, which can only be achieved by true effort and dedication (Practice makes master!).
Being active on the internet with other artists helps a lot also, we are in a very social business, and being nice and helping others reach their ultimate goals goes a long way!
Anyways, those are my 2 cents
