You interact with a fair amount of people on a daily basis in a variety of ways. Sometimes you see them face-to-face, sometimes you communicate virtually. Those interactions must be well chosen. You say yes to too much, and it’s costly. You are achieving less and are less focused than usual. You spend way too much time keeping up with your correspondences rather than working. You are putting what matters to the side because you feel obliged to reply.
Yes, you are compelled to answer. But who said you must respond now? Past that, who said that you have to agree to a meeting? Who told you to continue the conversation for hours on end? With people, you have to have a purpose in mind. Think beforehand about how you’ll end an interaction. Have an exit and take the exit. Return to your work. Return to what matters.
