Goal is 80lbs in 11 months. Need your help.

I could use some encouragement from others who have lost 50+ lbs or are attempting it as I am. I wish that kick in the *kitten* would come from my own brain, but the will power/gusto is not all there yet. Hopefully, it is coming soon! I've been on here only a few weeks, so far I have only lost 3ish pounds. I work at a 12 hour a day desk job, and need to get moving more. Any pointers, suggestions, words of wisdom, etc.. would be fantastic and greatly appreciated.
