99.999% of artists, some with education, some without, ends up working cashier at tattoo parlors, McD, Walmart, and Coffee Time. Many girls who have semi-amusing charms like me, end up working for tips at bars.
Just try to be happy. You don't neccesarily have to be overwhelmingly successful. Even having some crummy dead end job will suffice, as long as you can still do what you love. But I've seen your work, and I think it's fabulous; I doubt you'll have to settle for the lowest tier of things.
