The Laws of Human Nature
by Robert Greene
First, the Laws will work to transform you into a calmer and more strategic observer of people, helping to free you from all the emotional drama that needlessly drains you.
The truth is that we humans live on the surface, reacting emotionally to what people say and do. We form opinions of others and ourselves that are rather simplified. We settle for the easiest and most convenient story to tell ourselves.
Your first impulse should always be to find the evidence that disconfirms your most cherished beliefs and those of others. That is true science.
