I think he was saying the coup mentality is a destructive trait. Instead of focusing on what he is good at, masterminding, he was focusing on how to undermine the guy who assumed charge. By definition that's counter-productive. It's difficult to earn your (potentially invaluable) spot in the group when you "don't play nice with others".
Yeah, exactly. Until this was described to me via the KTS, I never really realized I was doing it. But on internal reflection realized it was a deep and pressing psychological need I had. I've found becoming aware of it has given me the tools to supress it.
I think that this tendency was sub-conciously "read" by others and growing up I rarely found myself in direct leadership roles. But after I started working on that part of myself, I think that vibe started to go away and I find myself in many more leadership roles these days.
