I've been trying to not suck at life myself. And you're right... I think it all comes down to moderation and motivation. It's just a shame that both of those things are FUCKING HORRIBLE.
Anyhow, good luck with the goals. I wish I had some advice, but I'm struggling myself. Fortunately, it's easier when you look down at your belly and actually see a difference every now and again. Sometimes on the elliptical or treadmill, I seriously glare at my stomach and think about how I'm going to murder the sonofabitch.
