Many people have been discouraged from being kind with entitlement mentality of some people.
In order to show kindness anytime and every time, we need to see kindness as part of the pillars of humanity. We are kind not for the accolades that comes with it but for the role that it plays in making the world beautiful.
Social interaction without kindness would be chaotic. I love the strategies that you listed for promoting kindness. That's amazing.
