Need the motivation!

Hi, I joined this thread over a year ago, but am just now getting into actually coming on here. I am looking to lose about 80 pounds, and am looking to make some friends on here with similar goals. I'm very interested in Zumba, I am currently unemployed due to a back injury and don't have much of an income, so I basically have to work with what i've got, but my big thing is I lack motivation. I'll have it for a couple days, then i'll just give up, and i'm tired of being that way, and need to make changes, and I need to make them now, I'd like to be at least a little bit more self appealing by the summer, so thats where i stand now!
Thanks for taking the time to read this, and if you are looking at similar goals, add me as a friend! :)
