Kindness with no limits eventually runs dry.

Generosity is a supply, not a personality trait, and a supply nobody refills runs out. People who give without any limit do not become endlessly kind; they get tired and then resentful, which is harder on everybody than an occasional no would have been. An edge is what lets the kindness last. The limit protects the very thing it appears to restrict.

Notice where you give the most and whether anything comes back. Trim one piece of it this week, not out of spite, only to keep the rest of it genuine.
