After a decade of failure, I finally made something—actually two things—that people actually wanted. I finally got it right. But it didn’t feel like success at first. Or even in the end. It was still work, every step of the way. Apple is where I learned where to draw the line—is it done enough? Is it good enough? It’s where I learned the real meaning of design. And it’s where I learned to organize my brain and my team in the face of intense, grinding, never-ending pressure.
