I think you have things a little mixed up. What you want to do with your art is have it as a hobby while you do something else to make money. So, you will need to put your hobby aside and do what it takes to make money to survive and any EXTRA time you have, spend that time on your art hobby. So, with that said, go to work in a art store. Deliver pizza's. If you are looking for a dream job/answer, I'm afraid it is just that... a dream. I know a guy that works at a very famous museum and would LOVE to be able to sell his art. But, he chooses to put life in this order.... family, work and then art. So, while he spends time on his art, it's not going anywhere because he doesn't put it first. He knows this, it has been discussed.
See, when a person wants to go in to a business and do something they love..... they are ALL IN!! It's not about, "Oh, it's going to be a lot of pressure and I don't want it to be pressure because I can't handle that. I don't want to have to bring home my work". If you want to make your art your life you WILL bring it home, atleast at first. That's what you think about 24/7. That's what you will do 24/7. That's what you will talk about 24/7. If you loved your art and wanted to make money with it, you would be doing everything about your art 24/7. But, you clearly said that is not the case, so what you want your art to be is a hobby and hobbies are done with EXTRA time.
Dreams are easy, real life isn't. This is just the truth, sorry if it comes off harsh.
