My background is in Hotel Administration, and that's how I learned that good service comes down to people. Reading what someone needs before they fully say it, staying calm when things get tense, and following through so they trust you the next time.
I brought all of it into Customer Success and Customer Service, and the part I enjoy the most is the human connection. In Customer Success I got to talk with people from all over the world, each with their own context and their own problem to solve.
I believe empathy is what carries you in any client-facing role. You can learn the product and the process but caring about the person on the other end is what they remember.
