Success involves more than a heart-pounding race to the finish line. Our research uncovered four irreducible components of enduring success: happiness (feelings of pleasure or contentment about your life); achievement (accomplishments that compare favorably against similar goals others have strived for); significance (the sense that you’ve made a positive impact on people you care about); and legacy (a way to establish your values or accomplishments so as to help others find future success).
