Last year I took part in a photo-a-day project. It was a huge challenge, not least because I work in an office full time so finding the opportunities was difficult but also the challenge just to keep taking a photo everyday.
I failed this project in the sense that I didn't take a photo every day, I spent a fair amount of time catching up. But I do have a photo for each day.
One thing that was a success is that because of this project I am now a lot more confident with my camera and also a lot more creative.
