All the walking I do around my campus during school is usually enough to wear me out during the week. During vacation times it kinda sucks though since I don't really have anywhere to walk around. I can take the dogs for a walk around the neighborhood or something sometimes, but they can't walk very far distances since they're small.
I try to watch what I eat, but I'm kind of a picky eater, so it limits my options. But... *shrugs* I don't think I'm doing too bad. I tend to just maintain my weight instead of gaining or losing.
