Please understand me is one of the most interesting and useful books I have found on knowing yourself and others. It helps in making life go smoother. An interesting book on intelligence by the man who started the PDA craze. On the subject of how brains work, I found this book extremely interesting. It gives an overview of how the brain works on those of us who are a little different (I am dyslexic).

Already read those? I generally suggest reading popular math or physics books.
