How to measure success

In our world today, success is often measured by material things...houses we live in, cars we drive, toys we have, vacations we take, you get it. Tonight, I have a new definition of success. We were in a room visiting with a patient when one of the nurses, a regular, I think her name is Ann, came in and said "Mrs. X is asking for you, she just got back today and wants to see the dog". That patients remember us and ask for us, that I can use the Chelsonator to make someone's day better, is a very high metric of success in my world.
