To design something really well you have to get it. You have to really grok what it's all about. It takes a passionate commitment to thoroughly understand something -- chew it up, not just quickly swallow it. Most people don't take the time to do that. Creativity is just connecting things. When you ask a creative person how they did something, they may feel a little guilty because they didn't really do it, they just saw something. It seemed obvious to them after awhile. That's because they were able to connect experiences they've had and synthesize new things. And the reason they were able to do that was that they've had more experiences or have thought more about their experiences than other people have. Unfortunately, that's too rare a commodity. A lot of people in our industry haven't had very diverse experiences. They don't have enough dots to connect, and they end up with very linear solutions, without a broad perspective on the problem. The broader one's understanding of the human experience, the better designs we will have.
