After following the lives of 268 Harvard undergraduate males from the classes of 1938 to 1940 for decades, psychiatrist George Vaillant concluded something you probably already know: Love is the key to happiness.
Even if a man succeeded in work, amassed piles of money, and experienced good health, without loving relationships he wouldn't be happy, Vaillant found.
The longitudinal study showed happiness depends on two things: "One is love," he wrote. "The other is finding a way of coping with life that does not push love away."
