The theory of positivity teaches us to, "always look on the bright side" and to, "point out the bright side to others". However, any highly empathic individual will know, that this mindset alienates us from other people. What connects us with other people is the ability to identify with what they are feeling and thinking, regardless of whether or not we've actually been in their place before. If you want to point someone out to the light, first you need to get into their dark cave with them, light a candle, and say, "Hey, I'm here with you and look, remember what the light feels like?" That's the kind of positivity that actually bears real change in people, in the world.
