If the only issue with taking up art is lack of an audience, that sounds like something to try. There are communities out there for artists (DeviantArt and some parts of tumblr come to mind off the top of my head, or any of a number of webcomic collectives) that will help you with that.

Also in general, it sounds like you're writing a lot of things off with 'I think that will fail, so I'm not going to try'. This seems counterproductive. Even if you have to try 10 or 20 things that each have a 10% chance of working for one to click, the process of trying things itself is likely to be beneficial in several ways. Think of it as information-gathering.
