Extreme Ownership is not only about leadership. It is about everyone owning what they are responsible for.
Every topic is tied to a stroy the author experience in the Iraq war and a scenario in a business setting. Sometimes it is not about winning or losing, it is about being responsible for oneself and for others.
Even if I am not in a leadership position, I am a leader in my own work. I am fully responsible for the outcome of my work.
I recommend this book.
