Martin Seligman, the father of positive psychology, theorizes that while 60 percent of happiness is determined by our genetics and environment, the remaining 40 percent is up to us.
In his 2004 Ted Talk, Seligman describes three different kinds of happy lives: The pleasant life, in which you fill your life with as many pleasures as you can, the life of engagement, where you find a life in your work, parenting, love and leisure and the meaningful life, which “consists of knowing what your highest strengths are, and using them to belong to and in the service of something larger than you are.”
After exploring what accounts for ultimate satisfaction, Seligman says he was surprised. The pursuit of pleasure, research determined, has hardly any contribution to a lasting fulfillment. Instead, pleasure is “the whipped cream and the cherry” that adds a certain sweetness to satisfactory lives founded by the simultaneous pursuit of meaning and engagement.
