Executive decision-making is a skill. Good executive decision-making seems to be a talent. These are neither skills nor talents that I was blessed with, but that's probably just as well. I've never been much of a leader, and never a good follower either. My major life decisions have always made me nauseous. Medicine has been the right field for me. Independent work, endlessly interesting, and cautious, careful, conservative decision-making comes easily to me.
From Harvard Biz School, "While elevated narcissism and self-promotion has been shown to result in quicker promotion early in one's career, its negative impacts are revealed in positions of higher authority."
As in the sports world, in the biz world, if you cannot produce winning decisions consistently and with integrity, you will eventually go down. It's rough out there. I hear all of the stories and all of the excuses, but the most talented and honest do pretty well and never make excuses for their disappointments. Competition is a big part of life, and an exciting part of it.
