I believe the article is oriented to those who feel like the "nice guy" the author is describing, which is my case, and expects you to act on how you feel to his words. I feel myself very reflected on the profile seeking for high affiliation, low power, and high emotional control; however, I am not sure to what extent should it only focus to a work environment.

Over the time, I have found myself more willing to fight over my "slice" of power in the workplace, making my demands assertively and showing that I know my value without traces of regret or false humility. That is something I have had to work on a lot, it makes me uncomfortable; but I understand that I "deserve" some power. If I am doing things right I cam claim my state for influence and being heard. I think this aligns with your point on being responsible with yourself and not just being a bystander.

On the other hand, there are other spheres in which I do not expect such power beforehand, so I'm not usually ready to draw my weapons. This may be a social encounter with barely-known people, friends, or even family. There are power fights there too, but somehow they feel different. Maybe I'm not as convinced of how I deserved such power, or maybe I'm not willing to do the effort anymore and I just want to fulfill my affiliation urge.
