I believe artists are born not made. The true artist will find a way to make their art. There is nothing wrong with working a straight job while also pursuing creative interests. I don't know why some think it has to be an either or choice. I work a job, play in a band, teach lessons and paint/ do exhibits .. When I am into painting I go full tilt..then after those manic periods of painting I'm back to guitar . I think being able to compartmentalize is a positive thing. Selling paintings is immensely satisfying but there is sometimes months between sales. Having a unobtrusive job with benefits is great for paying for art supplies and general living..bottom line you can persue art/music in a serious manner and still work.
