Dark force motivations, for me, have always been the things like anger, rage, channeled rage, insecurity, need for attention, accomplishment... And then there are light force points, which are 'I just love the work' ... Or 'I love the people I'm doing it with, or the sheer curiosity of the question,' or 'I know I can make this better, even if no one else notices, so therefore, I want to make it better.'
