Once you graduate from school, making friends becomes less of a given—it’s something you have to seek out. If you feel like your social circle is a little too small, it might be time to start reaching out.

One tactic is calling up old friends who have fallen out of your life. But this is also an opportunity to seek out new friendships! Get more active in your community—join a civic organization, a religious group, or a charity. People with diverse social support networks live longer lives!
