It hasn't hit a year mark but it's pretty close. The 365 Day projected ended in a bust. I think the hardest challenge was finding a photo to take without repeating. The same thing happened when I try just Prime himself but when I got laid off, it became even harder because I often times didn't really go out which limits what you can take. Then you run into the problem of "where do I go now" following.
Another year approaches, and don't know if I should try something like that or not. I tried to add accountablity via Facebook, but that didn't quite work. Something to consider for now.
