I highly recommend you watch the three-part series on Happiness and Emotion from PBS.
The human experience from the level of the nueron to the level of the neighborhood. The series interviews celebrities, doctors and tells some great stories.
Check out the full series on PBS or on Amazon Prime.
Money quote ‘I used to think that things would make me happy, or money. …..Happiness comes from within, happiness comes from experience with people that we love.’
