I would not use the term obsessive-compulsive which properly describes attention to rituals and details that don't have meaning or add to life (nobody ever got credit, much less world renown in any field, for having the cleanest hands in town or avoiding every fourth crack in the sidewalk).

However I've long held that most - not all, but most - people who actually devote their lives to something, anything, to the point that it changes the world are probably not the world's best parents or most skilled dinner companions. :-)
