Jeff Bezos outlines four key principles that define Amazon’s culture: 1) Customer centric—focusing on customers rather than competitors. 2) Long-term thinking—prioritizing extended investment horizons. 3) A drive to invent—embracing new ideas, even if they require trial and error. 4) Professional pride in operational excellence—maintaining high standards, even for unseen work. These principles are the foundation of Amazon, Blue Origin, and AWS, reinforcing a culture of innovation and execution.
