People are mesmerized by pure, unadulterated authenticity. When someone is comfortable & confident enough in their skin to be completely themselves, with no filter, it is extremely charismatic. Add in a lust for life and you have someone who will attract followers like a moth to a flame.
The problem, at least for most people, is that we are afraid to expose ourselves to this degree. We are probably as afraid of being loved as much as we are of being hated. It is much safer to hedge your bets and only reveal what you are comfortable with. This will protect you from having to deal with all of those messy people who want something from you.
The wild card here is the artist who truly doesn’t give a fuck. These people are simply uncontrollable, which has its own special allure. At the end of the day, they are probably the happiest.
