The Good Life: Lessons from the World's Longest Scientific Study of Happiness by Robert J. Waldinger and Marc SchulzRead about another entry on the list.
What’s the secret to happiness? It all basically boils down to relationships, and not just romantic ones. This book is written by the two Harvard researchers behind one of the most ambitious studies of all time, which for 80 years (and counting) has been collecting first-hand stories from one group of people through generations. This research—with a birds-eye view of entire lifetimes—puts science and data behind what feels unquantifiable: the behaviors that are the most fulfilling, what bring us the most contentment. It’s not the money, the cars, the big house, the impressive job, or the fancy clothes. Reading this will give you a newfound appreciation for the chaotic beauty of being alive.
