The first person you have to inspire every day is yourself. Running will do that. We're all terrible at something. Why not make up for it with a strenuous, completely unrelated activity? When you're nothing but a slob at the desk, you can instantly turn yourself around with a quick run. I've never been in a ditch so low that a run wouldn't pop me out of it. There are no shadings in this. Every run makes you fantastic.
