This is what I do - most of my picture taking is spontaneous, when I feel that I'm suddenly in a moment that would make a good picture, I'm aware of it, and it is a good moment to take a picture.

The trick for me is that I don't feel particularly compelled to have to take pictures to share with people. My experiences are for me first - to enjoy them, one would have to be enjoying them with me to get the full experience :) .
