Name one good thing in each of them

It's easy to walk into the morning huddle already annoyed. The whole crew shrinks down to a list of faults: he's slow, she interrupts, that one's always late. Carry that list into the room and you'll find exactly what you brought. Marcus knew the trap, and he knew the way out of it was deliberate — you have to go looking for the other thing on purpose.

His practice was simple enough to do standing at a time clock: "When thou wishest to delight thyself, think of the virtues of those who live with thee; for instance, the activity of one, and the modesty of another, and the liberality of a third, and some other good quality of a fourth" (Meditations 6.48, Long). The slow coworker never cuts a corner. The one who interrupts is the first to cover your break. The latecomer calms every panicked customer on the floor. None of that erases the faults. It just stops the faults from being the whole picture.

Do this before you deal with someone, not after, and you meet a real person instead of a grievance. The crew didn't change. Your eyes did, and that changes the room.
