Why do you do what you do? wdydwyd?

This site is exactly what the title says it is. It's a site where people submit stories, photos, tweets (#wdydwyd, and videos that tell why they do what they do). If you have some time, there are some amazing stories there, both in the form of short snippets (like the photo above) and some really interesting videos. So really, why do you do what 'you' do?

(For those of you doing New Year's Resolutions, looking forward to the new year, or reminiscing on the past year, this could be a great start to focus in on things.)
