Shoot with others, start to get that 'hmm, they waiting for me, I better hurry through this shot' etc type thinking. So yeah, shoot alone better. Sometimes my wife sits off somewhere else, watch the event etc while I go walkabout to shoot. Even then, is constricted by the 'hmmm, my wife waiting there very long liaoz, cannot dally too long here' thinking, which, sometimes, isn't very healthy for shooting.....
