I hope I understood your post correctly. I can definitely relate to your struggle to understand motivation. I'm currently going through that struggle as I am my own boss now.
I'm confused to where I stand in the dark and light worker spectrum. I believe that you can only help people if you help yourself first. People like and listen to people who are like themselves. The light worker seems like a person who derives his or her wellbeing from others. That to me just screams trouble. Nobody likes to have someone dependent on them for any reason. The dark worker works out of fear. I think fear cause unethical and destructive actions.
However, I may not be at my motivational peak. It's the first time to hear this idea of dark and light workers. You have much more experience than me, so I think I'll study and try out your ideas.
I may just need to reread the post. I'm a bit tired.
