I was very happy to have blurbed this new and wonderful book by Jonathan Rauch, here is one adapted excerpt:
Like adolescence, the happiness dip at midlife is developmentally predictable, and can be aggravated by isolation, confusion, and self-defeating thought patterns. Like adolescence, it can lead to crisis, but it is not, in and of itself, a crisis. Rather, like adolescence, it generally leads to a happier stage. In short, although adolescence and the trough of the happiness curve are not at all the same biologically, emotionally, or socially, both transitions are commonplace and nonpathological. But one of them has a supportive social environment, whereas the other has … red sports cars.
