The best part of the book were the inspiring stories of people actually being kind. The rest of itight be a bit of a snooze since, understandably, it covers the science behind how kindness affects human physiology. While I understand how some people can only be convinced with data, they weren't super exciting sections. That said, I'm convinced, but only to a certain extent. I know some people who cannot be changed at all because they are just, deep down, really really awful.
