Your customers, the people you look in the hairy eyeball and meet their needs. They are your best advocates. These people know the quality of your work. They know your focus and attention to what matters. They know when they see you you will deliver to them exactly what they have come to expect from you.
These customers know you and trust you. They are glad to see you and glad to have you be their person, worker, and friend.
Who are your customers (whether internal or external)? Who do you serve well? Who do you not serve well? How can you serve your customers better? What do you need to do to give your customers the best experience possible?
