" I’d always focused on the people most likely to be promoted. I assumed that was how it had to be at a growth company. Then a leader at Apple pointed out to me that all teams need stability as well as growth to function properly; nothing works well if everyone is gunning for the next promotion. She called the people on her team who got exceptional results but who were on a more gradual growth trajectory “rock stars” because they were like the Rock of Gibraltar on her team. These people loved their work and were world-class at it, but they didn’t want her job or to be Steve Jobs. They were happy where they were. The people who were on a steeper growth trajectory—the ones who’d go crazy if they were still doing the same job in a year—she called “superstars.” They were the source of growth on any team. She was explicit about needing a balance of both. "
