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.
Gretchen RubinPeople are powerfully moved by imagination, belief, and knowledge. They can consider the past and future. They can make changes in their behavior out of reason, in a way that animals canโt do.
