You do literally everything with your healthier body! Every moment of your life is lived inside a body which is more capable of physically influencing the world around you. A big physical change is like going from notepad to vim. It takes time and effort and attention but it's so damn _powerful_. Eating healthier and especially, _especially_ exercising is such a boon to generally feeling good throughout the day. I've never been more motivated, productive, and capable than when i was running every day. It was honestly astonishing.
