I spent nine years at Apple. It’s the place where I finally grew up. I wasn’t just managing a team anymore. I was leading hundreds, thousands of people. It was a profound shift in my career and in who I was. 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.

Your company is an organism; its cells need to divide to multiply, they need to differentiate to become something new. Don’t worry about what you’re going to lose—think about what you’re going to become.

You don’t get a growth mindset by proclamation. You move toward it by taking a journey.

Every lapse doesn’t spell doom. It’s like anything else in the growth mindset. It’s a reminder that you’re an unfinished human being and a clue to how to do it better next time.

Your life is not a thing, it’s an experience; the fun comes from designing and enjoying the experience. The reframe for the question “What do you want to be when you grow up?” is this: “Who or what do you want to grow into?” Life is all about growth and change. It’s not static. It’s not about some destination. It’s not about answering the question once and for all and then it’s all done. Nobody really knows what he or she wants to be.
