I've been pursuing a similar program for quite some time, and I'd love to see your take on it. I have a post on managing jealousy that I'm working on that'll address at least one part of the topic, but I would guess that we have approaches different enough that there's much mutual learning available.

And to second your general sentiment, I've found thinking rationally about my emotions and how to manipulate them to be not just useful, but literally essential for almost everything I want to accomplish. When I was younger I had extreme difficulties regulating my emotions, to a far greater extent than I believe is the case with most people, a problem that was likely due to my Asperger's Syndrome.

Constant analysis and experimentation over the years has now moved me to a point where I have exceptionally good control over my emotions, which has been nothing but positive.

TL;DR: I agree.
