I don't know exactly what it is. It's hard to say exactly how it feels but it just feels good. I'm always busy with one thing or another and it's so easy to put it off to the next day and the next day. When I do manage to scrape together the motivation to actually run, it feels so good. So good that while I'm doing it I say I'm going to run the next day and the day after that and the day after that. It never happens like that. I'd like to say that I'll get to a point where I'll run on a schedule every day that I say I'm going to. I can't imagine that ever happening. I've just got to remember that it feels so good.
