Jobs’s friend Larry Ellison, the founder of Oracle, had a private jet, and he designed its interior with a great deal of care. One day, Jobs decided that he wanted a private jet, too. He studied what Ellison had done. Then he set about to reproduce his friend’s design in its entirety—the same jet, the same reconfiguration, the same doors between the cabins. Actually, not in its entirety. Ellison’s jet “had a door between cabins with an open button and a close button,” Isaacson writes. “Jobs insisted that his have a single button that toggled. He didn’t like the polished stainless steel of the buttons, so he had them replaced with brushed metal ones.” Having hired Ellison’s designer, “pretty soon he was driving her crazy.” Of course he was. The great accomplishment of Jobs’s life is how effectively he put his idiosyncrasies—his petulance, his narcissism, and his rudeness—in the service of perfection. “I look at his airplane and mine,” Ellison says, “and everything he changed was better.”

“Remembering that I’ll be dead soon is the most important tool I’ve ever encountered to help me make the big choices in life,” he said. “Because almost everything — all external expectations, all pride, all fear of embarrassment or failure — these things just fall away in the face of death, leaving only what is truly important.”
