They eschew the notion of caring whether people like or hate them, only about being right/efficient/boss - but doesn't it make life an uphill battle?
Not only are people not going to jump to your aid (slowing/stalling your progress) - people can join together and oust you or backstab you.
Isn't it better to simply be diplomatic and assertive (not aggressive) and appeal to human psychology instead of stubborn insistance and intimidation?
You can get the same result...but faster, more surely, and lasting.
With the way I read about 8 behavior, I'd imagine that it'd be difficult for them to do anything - that everything they do, they have to struggle for. Whereas a 3 might be able to have people eager to move mountains for them. Less time struggling, more accomplishing. More efficient.
