Monet, Renoir, Degas, Cezanne; sound familiar? All had a little trouble getting their work accepted by the establishment. Do you feel comfortable in their company, if so worry not, and continue along your chosen path?
Rejection is the rule, acceptance the exception.
For myself I do participate in camera club life, as well as groups such as this, both because I enjoy the company of like minded individuals, and because I feel that I should put a little back into the pastime that I enjoy. As for my pictures, following advice from a sage whose work I much admire, I try to produce pictures that please me, rather than others; be they judges or not. Occasionally that which I produce finds wider acceptance, which is nice, but by no means essential to the enjoyment I derived from producing it.
