Positive cycle

I walked on the treadmill for 20 minutes this morning. I know that doesn't sound like a big deal, but it is for me. I've been on a negative cylce for a long time. I stopped exercising, which led to gaining weight, which led to feeling bad, which led to eating more, which led to not exercising, etc. I am trying to create a positive cycle so I'll lose weight, even if it's really gradual. I'm trying to eat less and exercise more, which will lead to feeling better, so I'll feel like exercising more, and who wants to chow down when they've just put all this work into exercising? So hopefully, I'll be more careful about what I eat.
