A self-learner from birth, I've always been intrigued with doing things outside my scope of study. A Formula 1 nut (wheelnut). A lover of exploring.

I feel this applies way beyond working in a start-up, it is in fact that being friends they have a soft spot in your heart, so it seems natural to get them on board and not want to let them off the team. However, there should be a fine line between friendliness and colleague wrt to roles and responsibilities.
