Extreme Ownership is the practice of owning everything in your world, to an extreme degree. It means you are responsible for not just those tasks which you directly control, but for all those that affect whether or not your mission is successful.
Extreme Ownership encourages people and leaders to:
Do not place blame elsewhere
Own your mistakes
Aim to continuously improve, because there is always room for improvement
Success is your responsibility
Do not complain, ruminate, or dwell because these are a waste of time Instead, take feedback from your predicaments and think about what you’ll do differently next time
Do not spectate at your own life; actively engage in it
Recognise that your decision and your habits have consequences
Have a good attitude
You’re more productive when you’re positive
Your attitude sets the tone for your environment
