Truely!!! Ego is the enemy in almost any situation especially in business!

Nailed it, @JoshuaRichards

I think his point can apply to any leadership or business role as well, in terms of being mission-centered or self-centered. As soon as you start to think that it's all about you, because you run the business or because you are in a leadership position, you stop making progress toward something that matters and you alienate the people who would help you get there (aka all the other people in the raft).

@soxfan2017 I'm with ya. The military is very good at teaching that way of life. Unfortunately, many who haven't served never get the opportunity one can only get from the military- which is why I believe this isn't taught as widely as it ought to be... People can't give what they don't have or teach what they don't know.

McRaven's advice can be applied to almost any professional field. Going from a big fish in a small pond to a large fish in an ocean (ex. high school to college athletics) can be very humbling, and those who succeed at the highest level simply learn to adapt and perfect their skills. Adaptability an important skill for succeeding in business, and this should be taught more widely.
