the most dazzling human achievements are, in fact, the aggregate of countless individual elements, each of which is, in a sense, ordinary. - Angela Duckworth

This brings me to the second part of the Hard Thing Rule: You can quit. But you can't quit until the season is over, the tuition payment is up, or some other "natural" stopping point has arrived. You must, at least for the interval to which you've committed yourself, finish whatever you begin. In other words, you can't quit on a day when your teacher yells at you, or you lose a race, or you have to miss a sleepover because of a recital the next morning. You can't quit on a bad day.

Of his early attempts at writing, Irving has said, "Most of all, I rewrote everything . . . I began to take my lack of talent seriously.

During his twenty-year professional baseball career, Seaver aimed to pitch "the best I possibly can day after day, year after year." Here is how that intention gave meaning and structure to all his lower-order goals: Pitching . . . determines what I eat, when I go to bed, what I do when I'm awake. It determines how I spend my life when I'm not pitching. If it means I have to come to Florida and can't get tanned because I might get a burn that would keep me from throwing for a few days, then I never go shirtless in the sun. . . . If it means I have to remind myself to pet dogs with my left hand or throw logs on the fire with my left hand, then I do that, too. If it means in the winter I eat cottage cheese instead of chocolate chip cookies in order to keep my weight down, then I eat cottage cheese. The life Seaver described sounds grim. But that's not how Seaver saw things: "Pitching is what makes me happy. I've devoted my life to it. . . . I've made up my mind what I want to do. I'm happy when I pitch well so I only do things that help me be happy." What I mean by passion is not just that you have something you care about. What I mean is that you care about that same ultimate goal in an abiding, loyal, steady way. You are not capricious. Each day, you wake up thinking of the questions you fell asleep thinking about. You are, in a sense, pointing in the same direction, ever eager to take even the smallest step forward than to take a step to the side, toward some other destination. At the extreme, one might call your focus obsessive. Most of your actions derive their significance from their allegiance to your ultimate concern, your life philosophy. You have your priorities in order.
