Focus on one thing, nail it. So when you really look at what you need to do, I think you've gotta do a body composition to start with so you really know your starting point. But then pick the thing, maybe the first thing for you as you go, you know, I've been sitting all the time. Your first thing's activity. Start there, focus on one thing, nail it. We had that discussion last time where I said it took me 6 months to get meditation under my belt. 6 months, I didn't focus on anything else, I just worked on that. So I don't focus on improving multiple things at once because then I don't do anything. One thing, one thing at a time.
