I've stopped looking at my photographs as bad, or good, and I treat them as sketches. Most of them are trial images to see if I am seeing what I think I am, and a lot of times they aren't. But, as with most of us, I try to learn something from all of them, even those that are less-than-successful. And I am reminded of Mike Johnston's comment, (of The Online Photographer fame,) that your contact sheets suck, and so did HCB's, and Gary Winogrand's, and everybody else's. It's part of the nature of the game.
Just my $0.02 worth.
With best regards,
