The musician playing with others needs to hear the room as well as their own part.

Playing well alone and playing well together are different skills. Inside your own part, correctness is the goal, but in a group the goal is the sound everybody is making, which requires spending attention outward rather than entirely on your own hands. Whoever cannot hear the room plays accurately and still pulls the ensemble apart.

The same is true well beyond music. In your next meeting or conversation, spend some of your attention on the whole rather than on preparing your own contribution. Notice what the group needs and adjust your part to fit it.
