Sometimes it's the tecnique, playing with a new setting, squeezing the AoF as tight as I can or following some principles.
Other times it's the process, getting me out of the house. It can sublimate cabin fever when it threatens.
Mostly it's the content. Your body of work is never done. It's important to continue to create and explore and express if only for yourself.
It's always a good thing.
I'm just glad I can create something. It doesn't have to be amazing, it just has to be honest. I like showing my pictures here and on Flickr, but the audience is mostly me and mostly unimportant.
