“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.”

“Of course it's not enough to sit around wanting to be happy; you must make the effort to take steps toward happiness by acting with more love, finding work you enjoy, and all the rest. But for me, asking myself whether I was happy had been a crucial step toward cultivating my happiness more wisely through my actions. Also, only through recognizing my happiness did I really appreciate it. Happiness depends partly on external circumstances, and it also depends on how you view those circumstances.-Gretchen Rubin”

“Another study suggested that getting one extra hour of sleep each night would do more for a person's happiness than getting a $60,000 raise.”

“One of the best ways to make yourself happy is to make other people happy. One of the best ways to make other people happy is to be happy yourself.”

“Because money permits a constant stream of luxuries and indulgences, it can take away their savor, and by permitting instant gratification, money shortcuts the happiness of anticipation. Scrimping, saving, imagining, planning, hoping--these stages enlarge the happiness we feel.”

“Studies show that in a phenomenon called "emotional contagion," we unconsciously catch emotions from other people--whether good moods or bad ones. Taking the time to be silly means that we're infecting one another with good cheer, and people who enjoy silliness are one third more likely to be happy.”

“According to current research, in the determination of a person's level of happiness, genetics accounts for about 50 percent; life circumstances, such as age, gender, ethnicity, marital status, income, health, occupation, and religious affiliation, account for about 10 to 20 percent; and the remainder is a product of how a person thinks and acts.”
