Many people believe happiness comes from money, or youth or beauty. Dan Buettner would respectfully disagree.
Buettner visited some of the happiest places on Earth and argues the real key to happiness comes from smaller, permanent changes in the way we live.
During a five-year study, the National Geographic Fellow located the world's happiest places — in Denmark, Singapore, Mexico, and California — and researched the characteristics those areas shared that improved the lives of residents.
Buettner lays out his findings in his book, Thrive: Finding Happiness the Blue Zones Way.
