Lent? To do or not to do?

Lent...
When I was little (talking middle school and high school)  I thought it was soooo fun and "cool" to give something up for lent. But, it was trivial....nothing that mattered, skittles, chocolate, note writing to my friends. Over the course of my (short) adult life I have thought every year on whether or not to participate. I do it as a challenge-40 days of commitment to SOMETHING. But its never for a religious purpose. So this year, my lent season challenge is to read my daily devotional every day (which is now put on top of my computer and I insist on reading it before anything else during the day. It's one on Single Mothering. Appropriate.)
....And to try to drop 15 lbs during this 40 day go-round. (basically focusing more on getting myself healthy.) I realize the latter isn't a "religious challenge" but its a needed thing and something I need to focus more prayer on getting back to the body God created and intended for me to have and less on my sugary, salty, bagely, monster cookie, pasta-y cravings. I think when I free my body of the excess weight (clearly more than 15 lbs needs to go but a girl can only tackle so much in 40 days) then maybe I'll free my mind of the self hate as well. Fingers crossed.

Are you participating? What are you giving up?
