The Protocol Principle Designing rules that optimize when and how coordination occurs in the workplace is a pain in the short term but can result in significantly more productive operation in the long term.

To summarize, I’ve presented two different ways people think about their working life. The first is the craftsman mindset, which focuses on what you can offer the world. The second is the passion mindset, which instead focuses on what the world can offer you. The craftsman mindset offers clarity, while the passion mindset offers a swamp of ambiguous and unanswerable questions. As I concluded after meeting Jordan Tice, there’s something liberating about the craftsman mindset: It asks you to leave behind self-centered concerns about whether your job is “just right,” and instead put your head down and plug away at getting really damn good. No one owes you a great career, it argues; you need to earn it — and the process won’t be easy. With this in mind, it’s only natural to envy the clarity of performers like Jordan Tice. But here’s the core argument of Rule #2: You shouldn’t just envy the craftsman mindset, you should emulate it. In other words, I am suggesting that you put aside the question of whether your job is your true passion, and instead turn your focus toward becoming so good they can’t ignore you. That is, regardless of what you do for a living, approach your work like a true performer.

Stanford psychologist Laura Carstensen, to name one such example, used an fMRI scanner to study the brain behavior of subjects presented with both positive and negative imagery. She found that for young people, their amygdala (a center of emotion) fired with activity at both types of imagery. When she instead scanned the elderly, the amygdala fired only for the positive images. Carstensen hypothesizes that the elderly subjects had trained the prefrontal cortex to inhibit the amygdala in the presence of negative stimuli. These elderly subjects were not happier because their life circumstances were better than those of the young subjects; they were instead happier because they had rewired their brains to ignore the negative and savor the positive. By skillfully managing their attention, they improved their world without changing anything concrete about it.
