No single bee controls the hive’s temperature. Thousands fan or shiver together. That’s what team culture is.

Nobody is in charge of what a group feels like. The atmosphere is the sum of a lot of small individual adjustments, each too minor to credit, and it shifts because enough people shifted slightly. Which means no single person can set it, and also that nobody is exempt from affecting it.

Pick your contribution deliberately this week instead of letting your mood pick it. Greet people, take the boring task, keep the complaining to one person who can do something about it. You are one of the thousands, which is both less and more power than it sounds.
