Need a push to work out

I've been wanting to loose those last 10 pounds since a few months now, but i'm not finding enough spirit in me to work out. I'm not overweight or anything, but I still want to get rid of 10lbs because its making me look bulky on unwanted places, and my clothes don't fit me anymore. I hope I can find something to push me to work out. I felt so horrible that I could fit in many clothes yesterday at the mall, which otherwise I would have worn them with ease and looked great. I want to really get back in shape.
