Just pretend you’re an agent of the company you work for rather than yourself, whenever you’re at work. Think of yourself always as partially an actor, and the script is whatever a good CEO would want you to do (also applies to things beyond human interaction), this helps me not take things personally but also generally do a better job and act more professionally.

If you remember part of the job is play acting this role, it can actually become fun as you learn more scripts and lines, and you’ll end up making a game of it.
