Doing good feels good because it is good! It is one of the things we were created to go. Kindness, compassion, generosity – these are things that were always supposed to come naturally to us. It’s a mark of how far humanity has fallen that often our hearts default to responses that are the exact opposite and can feel even more “normal” to us.
