Today, on Christmas Eve, some of us celebrate a joyful moment with friends and families. For some, this is a happy moment. One week ago, I asked you about the most significant driver of happiness, health, and longevity according to the most sophisticated longitudinal study on happiness, the Harvard Study of Adult Development ( or Grant's study). Among the three options, answer (2) would be correct, and I hope that today, you can enjoy this. 1. Self-actualization 2. Good relationships 3. Purpose in life. Because of this fundamental, empirical evident, and robust finding, our signature 10-day course, “Breakthrough for Senior Executives (BPSE)” at IMD helps leaders to define, and redefine, which relationships are important in business and life, and how to nurture them for the next breakthrough. www.imd.org/bpse Anders Fleischer Bettina Court Helle Bundgaard Brenda Steinberg Richard Westbroek Nancy Demaurex Chloé Maya Christopoulos Rolf H.
