Happiness and well-being are not just magical traits that some are blessed with and others not. Richard Davidson has come to view “happiness not as a trait but as a skill, like tennis.… If you want to be a good tennis player, you can’t just pick up a racket—you have to practice,” he said. “We can actually practice to enhance our well-being. Every strand of scientific evidence points in that direction. It’s no different than learning to play the violin or play golf. When you practice, you get better at it.”
