A friend of mine did this, and I thought it was a brilliant idea. Of course when I reviewed our pictures, I wished that we had more of them to choose from. I take a lot of pictures for any one occasion, but those occasions are not so frequent. I like the idea of taking a picture a day, but I am not sure I can commit myself to that. Maybe once a week. In any case, I think that I have decided upon a New Year's Resolution that sounds actually enjoyable: take more pictures.
