Emotional Intelligence: Happiness by Annie McKee, Gretchen Spreitzer, Daniel Todd Gilbert, Teresa Amabile

4.0

"As bird is born to fly, a human is born to be happy."

This book summarises recent researches in the happiness areas and shows interesting results. First, the pursuit of happiness does not make a person happy. Happiness does not improve performance.
There are links to scientific articles. However, since it is a review and not proper book, I'm not sure if there are no contradicting researches.
