All my life, I'd seen what one person — my mother — could do to help many others. I'd witnessed the power of purpose. - Angela Duckworth

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.

Three bricklayers are asked: "What are you doing?" The first says, "I am laying bricks." The second says, "I am building a church." And the third says, "I am building the house of God." The first bricklayer has a job. The second has a career. The third has a calling.

The first is that everyone — including Mom and Dad — has to do a hard thing. A hard thing is something that requires daily deliberate practice. I've told my kids that psychological research is my hard thing, but I also practice yoga. Dad tries to get better and better at being a real estate developer; he does the same with running. My oldest daughter, Amanda, has chosen playing the piano as her hard thing. She did ballet for years, but later quit. So did Lucy.
