Want to be happy? Get happy friends

Christakis also found that a person’s happiness is dependent not only on the happiness of an immediate friend but – to a lesser degree – on the happiness of their friend’s friend, and their friend’s friend’s friend. Furthermore, someone’s chances of being happy increase the better connected they are to happy people, and for that matter the better connected their friends and family. “Most people will not be surprised that people with more friends are happier, but what really matters is whether those friends are happy,” says Christakis.
