It is much easier these days to represent and sell your own work....without the need for going door to door. :)
I've only just rediscovered my enjoyment of drawing which is something I really loved doing when I was younger and am hoping that given time it might allow me the same freedom and control over my own life that you seem to have managed to achieve.
I'm hoping to try painting soon but that doesn't come as easily to me as the drawing seems to. :(
Selling my own work is far, far better than dealing with art galleries on a consignment basis. I have a billion nightmare stories I could tell about gallery owners and so does every other professional I know, although they continue to put up with it. I only have one such gallery and it's owned by my cousin, so we have no issues whatever, and she's the only one to whom I will EVER consign my work from now on.
At any rate, keep going @tonyr
