I'm super lucky in that I don't have depression myself or any history of it in my family. I consider myself a happy person and I do agree with that list for the most part. I find that I do most of it pretty regularly as part of who I am, actually.

I do have problems with comparing myself to others (mostly because I'm highly competitive), so that is something I've struggled with quite a bit over the years.

The funny thing is, I would say that I compare myself to others a lot less now precisely because I AM happy. I have a life that I have chosen for all it's craziness and even if it's not as prestigious, or travel-filled, or designer-label-covered, as some of my friends from college and high school, it's MY life and I'm glad that I have it. It's kind of self-fulfilling. Compare less so you can be happy or be happy and therefore compare less?

I think the same thing is true for exercise. Exercise more to feel better or feel better and therefore exercise more?
