We now know from twin studies that nearly half of our happiness is genetically inherited from our parents. Another 40% is dependent on the singular events, and that happiness is usually short-lived. It may come from achieving a goal or getting a bonus. The remaining 10%, however, is something that has a sustainable effect and you can control. That 10% depends on three factors: family, friends and work.
It is not surprising that family and friends contribute. But does work really? Apparently so. And it’s not the money from work that helps but the earned success at work.
So Franklin D. Roosevelt may have been right: “Happiness lies not in the mere possession of money; it lies in the joy of achievement, in the thrill of creative effort.” Decide the non-monetary currency you value (people, social contribution, self-development or something else) and then pursue that full-heartedly at work.
