I believe the point of the black box is to not be dependent on others for your happiness. Needing external validation to feel good about yourself is a serious mental issue. But, to you, it shouldn't really matter what I think ;)
Needing external validation to feel good about yourself is a fundamental characteristic of human psychology. The black box thing is about picking and choosing whose validation you care about and whose you don't. That's healthy. Genuinely not caring what anybody else thinks sounds more like sociopathy.
