SIX. Research indicates that just six high-value experiences a day will increase your happiness. Studies done at Oxford University show that at least half of your happiness comes from having a rich social network-a close group of people who truly care about you. Unsurprisingly, those who serve others tend to have the strongest social connections. In The Little Book of Happiness, noted neuroscientist Dr. Paul J. Zak shows you how to invest in relationships so you can truly thrive. Each chapter of The Little Book of Happiness defines one of the forty-five cardinal virtues, describes how it affects the brain, and provides scientifically sound practices for developing it. You'll also gain access to a free app to personally track your progress as you complete each happiness-expanding exercise. Discover how adding a daily dose of six-or more-quality experiences can change your life for the better!
