Acknowledgment index

An acknowledgment index is something a person might use to help keep track of when they do something nice for someone else. It means that when you do something kind or helpful to someone, you add it to the list. Then, when something good happens to you or someone else, you can look back at your list of kindness and see how you've helped other people. It is like a way to celebrate the nice things you do and the good things that happen to people.
