Spend Money on Social Activities
You've heard the old adage "two heads are better than one." This is never truer than when it comes to happiness. One of the most reliable causes of happiness, as it turns out, is other people. In a study comparing the happiest people with the least happy people, we discovered that having quality social relationships was the one factor that distinguished these two groups. It wasn't education or income or gender that set these two groups apart.

The happiest people tended to be those who had someone upon whom they could depend on a time of need or a close confidant with whom they could be honest and open. When you go about the business of spending money, consider bringing a friend along for the ride. Instead of lunching alone, try inviting a friend and see if those dollars do more than just buy a meal; they'll provide an opportunity for connection.
