Spend money on me--it's for your own good.

Elizabeth Dunn and Michael Norton write, Don’t Indulge. Be Happy.:

Imagine walking down the street to work and being approached by our student Lara Aknin, who hands you an envelope. You open the envelope and find $20 and a slip of paper, which tells you to spend the cash on something for yourself by the end of the day. Sounds like a pretty sweet deal. Now imagine instead that the slip of paper told you to spend the cash on someone else. Being generous is nice, sure, but would using the money to benefit someone else actually make you happier than buying yourself the belt, DVD or apps you’ve been dying to get?

Yes, and it’s not even close. When we follow up with people who receive cash from us, those whom we told to spend on others report greater happiness than those told to spend on themselves. And in countries from Canada to India to South Africa, we find that people are happier when they spend money on others rather than on themselves.

If people are happier when they spend money on others rather than on themselves, then should I ask them to spend money on me?
