Thank the people who treated you like the new you before you fully were. That kind of faith is rare.

Most people keep you in the file they opened years ago. Then somebody treats you as the person you are only halfway to being, and that behaviour does real work: it gives you somewhere to stand while the new version is still unsteady. They were not being naive. They were extending credit nobody else would.

Tell one of them, plainly, that you noticed. Name the moment they did it and what it let you do. People rarely find out that their small act of faith held something up, and it costs you one message to let them know.
