Creative You by Otto Kroeger and David Goldstein

I found parts of this book by Goldstein and Kroeger very helpful, for example, I liked the section on introverts.  However, I found the classifications which are based on the Myer-Briggs system rather rigid, and much of the advice a bit too vague.

However, it is a book that requires study, so I will read it again when I have more time.
