1. Why officers eat last

   In the United States Marine Corps there is an unwritten custom at mealtime: the most junior marines eat first and the officers wait until everyone else has been served. Nobody orders it.

2. O círculo de segurança

   Every human group lives with dangers from outside: competitors, a shrinking market, a new regulation. Sinek's key idea is that the real question is where the dangers inside the group come from.

3. A química das equipes

   Sinek explains behaviour through four chemicals the body uses to reward us. Endorphins mask pain so we can push through hard effort.

4. Cortisol e o custo do medo

   When we sense threat, cortisol floods the body to prepare us to fight or flee. It is useful for a moment in the jungle and poisonous over months in an office.

5. Abstraction makes us cruel

   Sinek revisits a famous psychology experiment in which ordinary people obeyed instructions to deliver painful shocks to a stranger they could not see. Distance made harm easy.

6. Coloque em prática

   This week, notice one moment when someone on your team admits a mistake, and respond in a way that makes it easier to do next time. Replace one metric driven update with a short conversation about what is actually getting in people's way.
