" We humans like to imagine that we have an objective knowledge of the world. We take it for granted that what we perceive on a daily basis is reality—this reality being more or less the same for everybody. But this is an illusion. No two people see or experience the world in the same way. What we perceive is our personal version of reality, one that is of our own creation. To realize this is a critical step in our understanding of human nature. "
― Robert Greene , The Laws of Human Nature
