#Zero to One by Peter Thiel and Blake Masters

####Chapter Notes on the book Zero to One.

• What important truth do very few people agree with you on? Brilliant thinking is rare but necessary. An appropriate way to answer this question is “most people believe in x, but the truth is the opposite of x”.
