Happiness
Do not believe that hard work and happiness are in opposition. Do not believe that one must embrace leisure to know joy.
Happiness is not a goal, it is a by-product. Paradoxically, the one sure way not to be happy is deliberately to map out a way of life in which one would please oneself completely and exclusively.
Harvard Study of Adult Development → Second Generation Study (since 1938): “The people who were happiest, stayed healthiest as they grew old, and who lived the longest were the people who had the warmest connections with other people. In fact, good relationships were the strongest predictor of who was going to be happy and healthy as they grew old.” (from Eat Your Ice Cream)
