Simplicity isn’t just a visual style. It’s not just minimalism or the absence of clutter. It involves digging through the depth of the complexity. To… - Walter Isaacson

Was he smart? No, not exceptionally. Instead, he was a genius. His imaginative leaps were instinctive,
unexpected, and at times magical. He was, indeed, an example of what the mathematician Mark Kac called a magician genius, someone whose insights come out of the blue and require intuition more than mere mental processing power. Like a pathfinder, he could absorb information, sniff the winds, and sense what lay ahead.

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.

The people who are crazy enough to think they can change the world are the ones who do. — Steve Jobs
