“The most impressive thing about this improvement in performance was that it did not come from a major process change or an advance in technology. Instead, it came through a leadership principle that has been around for ages: Simple.”

We wrote this so that the leadership lessons can continue to impact teams beyond the battlefield in all leadership situations—any company, team, or organization in which a group of people strives to achieve a goal and accomplish a mission.

We learned that leadership requires belief in the mission and unyielding perseverance to achieve victory, particularly when doubters question whether victory is even possible.

If mistakes happen, effective leaders don’t place blame on others. They take ownership of the mistakes, determine what went wrong, develop solutions to correct those mistakes and prevent them from happening again as they move forward.

The U.S. Navy SEAL Teams were at the forefront of this leadership transformation, emerging from the triumphs and tragedies of war with a crystallized understanding of what it takes to succeed in the most challenging environments that combat presents.

Cover and Move, Simple, Prioritize and Execute, and Decentralized Command.

Establishing an effective and repeatable planning process is critical to the success of any team.

The test for a successful brief is simple: Do the team and the supporting elements understand it?

Staying ahead of the curve prevents a leader from being overwhelmed when pressure is applied and enables greater decisiveness.

A good leader does not get bogged down in the minutia of a tactical problem at the expense of strategic success.

His realistic assessment, acknowledgment of failure, and ownership of the problem were key to developing a plan to improve performance and ultimately win.

There is only hard work, late nights, early mornings, practice, rehearsal, repetition, study, sweat, blood, toil, frustration, and discipline.

Leadership requires finding the equilibrium in the dichotomy of many seemingly contradictory qualities, between one extreme and another.

A mission statement tells your troops what you are doing.

People do not follow robots.

A good leader has nothing to prove, but everything to prove.

If we could execute with a monumental effort just to reach an immediate goal that everyone could see, we could then continue to the next visually.

Love does not die, when someone gets old, people get old, because they can not love anymore.

I’ve loved my 20s, but I would never repeat them.

I look back at my twenties and see that I was much less confident.

I guess I started running when I was about 18 and… I feel like it assists my creativity a bit because it completely just flushes everything out.

I stepped into the martial arts movie market when I was only 16.

Dressing up is a bore. At a certain age, you decorate yourself to attract the opposite sex, and at a certain age, I did that. But I’m past that age.

We remained youthful never aging a single second because we promised each other that we wouldn’t.

I started piano when I was four. My mom taught me. And then I went to Manhattan School of Music during high school, like every Saturday. And then I went to Berklee for college, in Boston.
