"Musk, though, approaches everything from a Platonic perspective. As he sees it, all of the design and technology choices should be directed toward the goal of making a car as close to perfect as possible.
...It's almost a binary experience for him. Either you're trying to make something spectacular with no compromises or you're not. And if you're not, Musk considers you a failure." [emphasis added].
From the excellent book, Elon Musk: Tesla, Space X, and the Quest for a Fantastic Future." Ashlee Vance
