Greg,
First find a work out buddy is probably the best thing since a husband or wife. Find somebody motivated/and or more motivated than yourself and tell them to push you, vice versa. It works. You don't need to go to the gym (I haven't really read the whole thread) so I'm sure somebody has said that.
Motivation? I dunno what you look like, I'm sure you look fine, but imagine yourself even better than now. Shoot a goal for the summer, loose 10 pounds by the end of June? You can run 3 days a week, or even just diet. If you want to lose fast I'd suggest some sort of negative carb diet, literally no carbs, the fat will fall off like an eroding cliff promise. There are other various diets (all about personal pref) and way to cut fat really quick, or slow. You must be diligent and never falter from the path of the diet though, or else your metabolism won't recreate itself.
I don't know how to quell your boredom, for me, I just bring my ipod and usually brainstorm story ideas or something.
I'm pretty amazing, thank you
