It’s complex, it’s subtle, it defies explanation but it’s not magic. It’s a process that requires a degree of faith and fortitude. It’s collecting but ignoring data and trusting judgement when data tells you to move in a different direction. It’s a lot of willful rejection of conventional wisdom. It’s asymmetric approaches to competition. It’s art as much as science. And most of all, it’s a lot of mind-numbing polishing while trusting that only by doing great work is survival even possible.
