There are interesting photos everywhere you look, all you need to do is see them. I find myself looking at everyday items in a whole different way as I go about my day. I was on the deck of the U.S.S. Kidd with a friend shooting one day and saw a coil of rope criss-crossed on a stanchion and stopped to photograph it. later, when my friend saw the photo he said that he saw me take the shot and was wondering what it was that I was seeing. He loved the shot, and it makes a point that you never know when a seemingly normal item will make a good photograph.
If you take the time to look around, you'll see that there are photos everywhere, like I said, all you need to do is see them.
