Nature
I find nature a lot of fun to take photos of. You can make a weed look beautiful and pure. Then also make something you go to everyday make it look completely unrealistic looking. I have gotten a few comments about my "Liter" part of this page. They enjoyed how I made liter and actual interesting photo. You can really make anything into an interesting photo. Your vision is your vision of the image, and if you can make your vision come to life, then that will be one amazing piece!
