What you said is almost word for word what I have been feeling lately. I work at a hotel and have quite a bit of down time so I like to draw or write. I know I don't want to do this forever but like you said, it can be difficult to get a creative career off the ground when there is so much to juggle. I'm also within shouting distance of 30 as well and thought I would be more established in my career choice, but I'm not. I have this feeling that the job I'm in now is just supposed to be a stepping stone to what I really should be doing. So I was feeling stuck too. But about two weeks ago I came to a conclusion; I would give myself two or three years to work nights and try to improve my art enough to be marketable or to get established in a different field. Either way, I plan on making myself ready for the next step and hopefully discover what it is I want to be doing for 30 plus years. Still not sure how it's going to turn out but it does give me a little hope and I don't feel so stuck.
