Out of eight billion people, nobody else can show up for your people exactly the way you do.

Replaceable at a task and replaceable to a person are two different conditions. Somebody else could cover your shift tonight. Nobody else has your history with your sister, your particular jokes, the shorthand that took years to build. For the handful of people who are yours, there is no substitute available anywhere.

Pick one of those people and do the thing only you would do for them this week. The specific reference, the thing you remember that nobody else does, the help nobody else would think to offer.
