I suspect working with someone only works when the someone you work with is goal driven by a goal that matters at least a little bit to you. I have no one who shares my goals enough to both 1) want to work alongside me 2) be among those whom I'd have working alongside, if given a chance.

BTW my goals can 90% be achieved alone in the sense of without a partner, but not in the sense of without a motivational human driving force.
