Many years ago, as a new assistant at Lord & Taylor, the buyer cautioned me to not get too attached to people or merchandise. His wisdom was not cold-hearted, but a cautionary tale to keep emotional attachments in check. I was there to deliver strong financial results and if something wasn’t selling, I shouldn’t harp on it, but mark it down and move on. And, as far as work relationships were concerned, I should be a good coworker but not get attached to colleagues.
