As a kid I actually used to think that everyone thought like me, or would think like me, if only they would stop wasting so much time on silly things like pop culture and trendy clothes and social drama and spend more time cultivating their awareness of the world around them. I was convinced that if people could only be awakened to their inner authentic self, they would all see things my way.
Ha ha, I'm not sure now if this was my idealistic streak or sheer narcissism. Because clearly mine was the superior mentality.
I think that everyone has the potential to exhibit mental illness, regardless. That said, I do myself take medication for attention deficit. It allows me to be a vastly more productive and capable person.
