I've been participating in flickr's 365. You take a self portrait every day for 365 days. Part of the purpose of this is to keep photographers actively taking photos, and exercising their creative skills too.
I'm not real big on photos of myself, but here is one shot where I actually have most of me in it, (without some kind of textures or crop to mask me). ;)
Something fun, and it is definitely a commitment to creativity. :)
