This was a powerful book with up-to-date research and ideas for how to connect our communities in an increasingly isolated world. It's easy to think "oh, that's for other people - I have plenty of friends" - and Murthy compellingly addressed that attitude, showing how deep connections are more than just someone you can technically call a friend. How many times have we hesitated to call our friends when we actually need help because it could bother them? And though loneliness affects everyone at some point, the solutions can also start small, with anyone: a kid can invite someone to sit by them at lunch.
