To not move around, observe, and analyze, in order to make the best decisions possible, was to fail as a leader and fail the team. - Jocko Willink

In protecting my boat crew, I actually sheltered a couple of perpetual underperformers who dragged the rest of the boat crew down. When Hell Week was over, talking to some of the other members of our boat crew, we realized we had carried along these mentally weak performers. They almost certainly would not have met the standards otherwise. That loyalty was misguided. If we wouldn’t want to serve alongside our boat crew’s weakest performers once we were all assigned to SEAL platoons in various SEAL Teams, we had no right to force other SEALs to do so. The instructors were tasked with weeding out those without the determination and will to meet the high standards of performance. We had hindered that.

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.

any team, in any organization, all responsibility for success and failure rests with the leader. The leader must own everything in his or her world. There is no one else to blame. The leader must acknowledge mistakes and admit failures, take ownership of them, and develop a plan to win.
