Similarly,the Science study found that spending a small amount of money could bring large results.In a separate experiment,the researchers gave college students either 5 or 20 and told them to quickly spend it on the money. Some were told to spend it on themselves-on. A bill or agift to themselves . And some were told to spend it on others-on a donation to charity, or a girt to someone else . The vast majority of the students predicted that they would be happier with $20 that $5.
