Kindness nobody sees is the cheapest investment with the highest return.

Unseen kindness is the only kind with no performance in it, which is exactly why it does something to you. Holding a door, cleaning up a mess that is not yours, saying the good thing about somebody who never hears it: none of it costs anything and none of it can be collected on. What it changes is the default you run on.

Do one of these a day for a week without mentioning any of them. Not for credit. Just to find out who you are when there is no audience.
