Ever hear of the 365 Project? It's an idea where you document a year of your life by taking a photo every day. (More info can be found here: http://365project.org/)
Now, as writers, maybe y'all don't think this would be something you'd be interested in, but give the idea a chance. We're not talking super great well-composed pictures here. We're talking just photographing something that illustrates your day; a cloud, a frozen dinner, a bird...whatever. Looking back on these pictures may give you some great ideas for stories, essays, poems, songs...who knows.
I'm starting my 365 Project tomorrow. What about you?
