Just because you drop out of college doesn't bar success -- Steve Jobs made home computing easy, Mark Zuckerberg pioneered social networking, and Bill Gates invented the damn window. For a dropout graphic designer successfully arting your existence, check out Tom Burns.
After fleeing the intolerable drinking and conscience-free sex at MTSU, Burns began designing for a Murfreesboro t-shirt shop before busting out to produce prints and tee designs, eight of which attained best-seller status on Threadless, a feat that even impressed Tom's hard-to-please father, C. Montgomery. His printed-on-archival paper designs have fun with phrases like "Spaghetti Western," which features a cowboy using a strand of pasta as a lasso while chillin' atop spaghetti and meatballs, and "Communist Party," with noted enemies of the state including Mao, Lenin, and Stalin chugging from red Solo cups, which explains why McCarthy drank only from Ameri-cans. He's also pushing laptop/iPhone skins, including "1975," which at first glance appears to just be a floral pattern, but reveals a hot chick's face when examined closer, and "E=M.C. Escher," where Einstein's head looks kinda like a paper Slinky, so make sure not to stretch him out too far or he'll stop working right, and you'll realize how boring stairs are.
Two of Burns' shirts are still currently up for sale on Threadless, and he's also available for your graphic design needs, from corporate logos to album layouts, like the one he did for middling NFL tight end/Contemporary Christian artist Ben Utecht, a guy who actually went to college for four years -- one way to ensure you won't be a successful athlete.
