Tell me anon, what goal are you working towards?
What point in time or event in the future do you lose the weight for (if any)?
Want to be able to go to the beach and not feel shame next summer?
Got an appointment you want to look good for?
Someone in your life you're doing this for?
Or just for yourself?

In my case one of my oldest and best friends asked me to be the best man/groomsman at his wedding at the end of this year, and while I probably won't manage to reach my goal weight quite until then, at least I want to get close enough to be in the range of acceptable girth. I'll be damned if I won't be there for him on his big day or fuck it up somehow because I am fat.
