And a better statement of why I'm interested in selling my photographs couldn't be made. All my life I've labored at tasks I wound up hating, making other people rich. Here, I see the glimmer of hope that I might finally be able to live the dream of making my living doing something I'd do if I had to pay to do it -- and even if I never make a living at it, it'll be a lot easier to keep doing it if I can at least make it self sustaining.
I don't know if I can market my work well enough to make this a reality -- or, really (until I try it) whether my work is really good enough in itself. But if I don't try, in another thirty years I'll be old, decrepit, half-blind, and bitter, and photography will be just another thing I used to enjoy. Might be the case anyway, of course...
