Your description summarizes what I've been trying to express so concisely – it's almost shocking. I'm left wondering on what side of the split you stand on.
I have far less of a normal life than most people and am far more obsessive about the kinds of things I do spend my time on than most people, so I don't personally bond that easily nor enjoy the casual moments or marshmallow and spaghetti tower building.
I enjoy objectives and racing towards them.
