For it is in giving that we receive. – Francis of Assisi
「我們因為給予而獲得。」─ 亞西西的方濟各（編按：天主教聖人）
Indeed, treating ourselves to something nice can make us feel good. However, recent research has shown that prosocial spending—spending money on others—can lead to an even greater sense of happiness and well-being.
Research into prosocial spending is relativelynew, but the results are conclusive. __1__ Further, it helps contribute to a sense of community and belonging. In a study conductedby psychologistsat Harvard Business School, passersbywere handed an envelope. When people opened the envelope, they found a five-dollar bill along with a simple note. __2__ Others found a note that told them to spend this five dollars before 5:00 p.m. on a gift for someone else or a donationto charity.
Later that evening, participantsreceived a call. __3__ The result was that individuals who had spent the money on others were measurablyhappier than those who spent it on themselves.
Numerous other studies have demonstrateda consistentlink between generousspending and happiness. This is true regardless of age, culture, and socioeconomicstatus. __4__ Namely, spending money on others results in the most happiness when one of three conditions is met: when spenders choose freelyto offer help (rather than being asked or forced to do so), when spending offers the opportunity to connect with others, and when spenders are able to see the positive influence of their generosity.
(A) They were asked about their overall mood throughout the day, as well as how they had spent the cash.
(B) Some received a message that instructed them to spend the money on themselves before 5:00 p.m.
(C) There are, however, specific conditions that are more likely to promote greater amounts of happiness.
(D) Giving to others impacts the happiness of the giver and the receiver.
