You are working at a great pace on your own right now, so there is no reason for you to change. Why start working in teams? The other people involved could get you off your rhythm and you might end up wasting more time than you'd like, dealing with difficult personalities and the bureaucratic issues that evolve when there are more than two people working together. If you can't stick to yourself right now, then at least try to be the quietest one in the room.
