I've just read NeuroWisdom: The New Brain Science of Money, Happiness and Success, by Mark Robert Waldman and Chris Manning.
The book covers current neuroscience on how to be happier and more successful, usually with simple techniques you can use every day that were proven to work on actual research.
I can't say I got around to trying most of the ideas yet, but I certainly intend to, and several I have heard from several sources.
Overall, seems well worth the time reading and applying.
Read from Safari Books. Formatting was fine (I just saw a single book that had some formatting problems this year).
Update: It was removed from Safari.
