Remember: van Gogh was undervalued while he was alive. I guess he should just have thrown his stuff away early and become a baker. Mozart had virtually non-stop money troubles, even before he started becoming a party animal, and died a pauper who was buried in a linen sack in a mass grave. Guess he would have had a better life being a potter.
Art is something that may only be valued highly ex post facto, and which takes a long time of intensive training to get started...
