Cliveh, not sure if I got the right understanding of the topic. What I do is I go out, take a camera, go to the location and let the subject come to be, reveal itself.
I try to look at the scene from every angle and compose in my mind so I can tell the story. If I'm not inspired I don't shoot (I may have a bad day or the subject is not as interesting as I thought).
I don't take pictures because I decided to do so when I left home - every time I tried that it didn't work.
I take pictures because I'm impressed by what I see. If you look carefully there are lots of intersting subjects all around us.
