" Trust your internal observations too much and too long, and you might be in for a very rude awakening. Second, we believe that our introspections are more reliable than those of others, which creates an illusion of superiority. Remedy: Be all the more critical with yourself. Regard your internal observations with the same skepticism as claims from some random person. Become your own toughest critic. "
