It breaks down emotional skills into personal competence skills -- self-awareness and self-management -- and social competence skills -- social awareness and relationship management. It's accompanied by an online assessment that gives you a score in each of the four areas, and helps you devise a plan to improve in the areas you need. It also discusses over a dozen strategies in each area that you can practice to improve.

So far, I really like it, it's very straightforward and the strategies it offers are really concrete and not terribly difficult to practice. My partner is also reading it, to support my own efforts (I need it more than he does), he is further along into it than I am and he's also been really impressed with it so far.
