I have almost all my walls covered with other photographers work on it. I want to have work that inspires me, makes me stop and slow down and see what wonderful work is seen and done. I have my library too.
Then I grab my gear and go forth and try to do my work.
I once attended a lecture by Carol Burnett and she shared that she stays fit by playing tennis. She likes to play against someone who is a better then herself. Gives her a challenge.
I like to think that the work I have on my walls does this to me. And what I see on APUG's and other website galleries do for me as well. I'm trying to better myself by seeing work of others who I admire.
