Had a friend say to me one time "I will never be a great photographer"
I think this statement sort of misses the point at least as I see it. The point is not about you but should instead be about the photograph. The reason to do photography as I see it is to make great photographs. You make photographs to create lasting, important images. It is not about the photographer it's all about the photograph, that is all that matters.
The goal is not to be a great photographer, the goal is to make GREAT PHOTOGRAPHS.
