Take a break. Read a book, not about photography. Travel. Put the camera down. Pick one photographer,only one, and look at his/her photos. Imagine yourself in the same location, and try to comprehend why they put the camera in that one spot, that light, that moment, that print.
My thinking is that for me,photography is about the world outside of me and how I 'position' myself in relation to that world. Position in the broadest sense-not just physically, but intellectually, emotionally, historically, etc. And sometimes I (excuse me here) can crawl so far up my own rear end that I lose sight of what makes photography interesting to me.
So I take a break.
