Gretchen Craft Rubin (born December 14, 1965) is an American author, blogger and speaker.
The belief that unhappiness is selfless and happiness is selfish is misguided. It's more selfless to act happy. It takes energy, generosity, and discipline to be unfailingly lighthearted, yet everyone takes the happy person for granted. No one is careful of his feelings or tries to keep his spirits high. He seems self-sufficient; he becomes a cushion for others. And because happiness seems unforced, that person usually gets no credit.
Although people sometimes assume that the happy are self-absorbed and complacent, just the opposite is true. In general, happiness doesn't make people want to drink daiquiris on the beach; it makes them want to help rural villagers gain better access to clean water.
