If you want motivation, go climb some stairs and see how quickly it takes for you to get tired. Better than looking in the mirror.
anyway, I'm not trying to be as fit as the other guys here. I work out, exercise, w/e because it's mostly part of a routine now. I still do it to improve, but 3/5th of the reason kinda seems to just maintain. As for eating better food, that was pretty easy since healthier foods are tasty (see rest of thread and greek yogurt praise). Just break out of bad habits and form better ones. May be harder to do that for others, so I won't judge.
