We all learn right from our childhood that we must be good human beings. That entails, being kind to other people, helping them out, spreading love and joy in the world, and stuff like that.
This is what we have been taught, but it isn't the reality, being that much of kind these days may get you killed, I think in today's era to be happy we must not be too concerned about others. And for those who don't care about us, we shouldn't give a shit to them. Practical life is quit different from what we have been taught in childhood
