Quality friendships are better than quantity

Having lots of friends does have benefits. Research shows that people who regularly interacted with 10 or more friends in midlife have higher levels of psychological well-being than those who had fewer than 10.

But you don't need dozens of friends to enjoy the fruits of friendship. Even having one friend is a net positive. Instead of trying to keep in contact with everyone you've ever met, consider the value of a few close confidants.
