Love psychology. I stick mostly with positive psychology and development psychology. The abnormal psychology stuff is a lot of personality typing really. Not un-useful but to me, less useful.
abnormal psych is fun, but you’ll be able to self-diagnose everybody with at least three conditions – and constructivist psychology, while a bit fluffy, is useful – otherwise, you’ll just be putting stickers on everybody, calling up a psychiatrist and getting everybody pumped up with questionable pharmaceuticals.
