During the crossing, Einstein explained his theory to me every day, and by the time we arrived I was fully convinced that he really understands it. - Walter Isaacson

"Some people say, "Give the customers what they want." But that's not my approach. Out job is to figure out what they're going to want before they do. I think Henry Ford once said, "If I'd asked customers what they wanted, they would have told me, 'A faster horse!'" People don't know what they want until you show it to them."

The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything.

Jobs's intensity was also evident in his ability to focus. He would set priorities, aim his laser attention on them, and filter out distractions. If something engaged him- the user interface for the original Macintosh, the design of the iPod and iPhone, getting music companies into the iTunes Store-he was relentless. But if he did not want to deal with something - a legal annoyance, a business issue, his cancer diagnosis, a family tug- he would resolutely ignore it. That focus allowed him to say no. He got Apple back on track by cutting all except a few core products. He made devices simpler by eliminating buttons, software simpler by eliminating features, and interfaces simpler by eliminating options.
He attributed his ability to focus and his love of simplicity to his Zen training. It honed his appreciation for intuition, showed him how to filter out anything that was distracting or unnecessary, and nurtured in him an aesthetic based on minimalism.
