Get after it. - Jocko Willink

You can’t make people listen to you. You can’t make them execute. That might be a temporary solution for a simple task. But to implement real change, to drive people to accomplish something truly complex or difficult or dangerous — you can’t make people do those things. You have to lead them.

Every moment you are alive is made of choices you get to make.
Little, tiny choices that alone mean nothing, but when combined together, mean everything.
You have to make the right choices. The hard choices.
You have to deny immediate gratification and pushback against weakness.
You must impose Unmitigated Daily Discipline in all things.

The book derives its title from the underlying principle — the mind-set — that provides the foundation for all the rest: Extreme Ownership. Leaders must own everything in their world. There is no one else to blame.
