Captain David Marquet was used to giving orders. In the high-stress environment of the USS Santa Fe, a nuclear-powered submarine, it was crucial his men did their job well. But the ship was dogged by poor morale, poor performance and the worst retention in the fleet.

One day, Marquet unknowingly gave an impossible order, and his crew tried to follow it anyway. He realized he was leading in a culture of followers, and they were all in danger unless they fundamentally changed the way they did things.

Marquet took matters into his own hands and pushed for leadership at every level. Before long, his crew became fully engaged and the Santa Fe skyrocketed from worst t first in the fleet.

No matter your business or position, you can apply Marquet's approach to create a workplace where everyone takes responsibility for their actions, people are healthier and happier - and everyone is a leader.
