Motivating a Motivator

I don't know if anyone has to deal with this, the way that I do, but I'm sure other people have to deal with motivation. They say that humans are creatures of habit, but I don't think that's entirely accurate. There are some who say that if you do something long enough, "routinely," it will become second nature and habit forming. They say if you do something for three weeks, or for a few months. But for me, I have to force myself to do things everyday. I still have to talk myself into brushing my teeth. Which, I do, every day. Starting this spring, I was going swimming every day. And every day, I'd get ready and get out there, and then; standing at the edge of the pool, I'd have to hype myself up to jumping in. This started back in April, it's now July, and I still have to talk myself into jumping in. Last year, I put myself on a strict exercise regime, and I did it from May until September. That whole time, I had to talk myself into it every day. Yes, some days were easier than others, but as soon as life got stressful, I was unmotivated to motivate myself to keep trying. As some know; I'm trying again with the exercise thing. Since my circumstances of living are significantly different now, It's much more difficult to actually Do what I think I should and to stay on track. In other words, this time around; my self conscious self gets in the way. Though I recognize this, that doesn't make it any less difficult on a daily basis. I'm also not receiving any outside motivation either, actually; at times, it's quite the opposite. That's actually part of the reason for me making my healthyvan.blogspot.com blog. Also the reason for the 10 day check-in videos on my Ceeyena account on Youtube. It's also the reason I'm putting actual photos up of me in all my fatness as well. I'm trying to trick myself into being motivated and just do it. Hasn't really worked yet though. 
However, I have assumed the role of the motivator for Mr. Peanut. I can figure out the right, true, things to say when he needs it. Most days it's easy for me to motivate someone else, especially if I believe in them. Maybe that's the issue, right there... I don't believe in me.
