When I began to use a dSLR, I was hanging out on a computer forum with a section dedicated to photography. There was a few Pro hanging there, the kind who studied photography and couldn't bare to see amateurs using cameras, the kind who shut you down each time you post something they deem crap (About everything which wasn't posted by them). Needless to say that it was a destructive environment, I stopped to share my pictures and it took me a few years to start doing it again. I eventually realized that my pictures didn't need to be contest material, they didn't need to be perfect, they just needed to please me even if only a little. This (and not paying attention to elitist shenanigans) helped to get confidence and to improve.
Ps: I hope this fall within the scope of this thread?
