Old grudges take up space you need for new people. Let one go and see what moves in.

Carrying a grudge is not free. It takes attention, rehearsal, and a small ongoing decision to keep someone in the role you cast them in years ago. That upkeep uses the same capacity you need for the people who are actually around now.

Choose the oldest one you are still carrying, the one where the details have gone fuzzy. Letting it go does not require a conversation or forgiveness said out loud. It only requires stopping the rehearsal, and a month of that will show you who fills the space.
