actually think you learn a lot more from your successes [than your mistakes]. There are a million reasons why something can fail, but usually very few reasons why something can work. When you want to learn to be a great runner—do you study slow people or fast people? I think taking time to understand why things succeed—whether they are your successes or others—is time well spent . . . you learn the most from things that go really well by asking why. Those are the things you want to understand and do more of.”
