If #4 is expanded to "Be charismatic and social", that would cover #6 and #7. I think #5 and #8 are part of #3, being in the right geographic location is definitely part of being the prevailing tribe, and so is having up-to-date tech skills.

Come to think of it, #2, being easy to work with, can be subsumed into being charismatic and social without much loss.

"Easy to work with", "member of the tribe" and "charismatic" are separate categories because the model is intended to embody the truth that social factors dominate, and to give hope and direction to those who are never going to be members of the tribe. :-)
