Page shared a counterintuitive insight from his experience building Google: the biggest dreams often face the least resistance. He learned the principle of having a 'healthy disregard for the impossible' from a Michigan program called LeaderShape, which had encouraged him to pursue the crazy idea of building a personal rapid transit system on campus. He explained that so few people are crazy enough to tackle truly massive challenges that he felt like he knew them all by first name. They travel like pack dogs and stick to each other like glue, because the best people want to work on the big challenges. Google's mission to organize the world's information nearly didn't happen because he and Sergey were too worried about dropping out of their PhD program.
