Leave the locker room, the kitchen or the shared doc better than you found it. People remember who did that.

Shared spaces run on a small number of people who do slightly more than their share, and everyone can eventually name them. It is not really about tidiness. It is a signal about whether you treat common things as somebody else’s responsibility, and people generalize from it to how you will behave when something larger is shared.

Do one unclaimed improvement wherever you land this week. Wipe the counter, fix the broken heading, put the equipment back properly. Small enough to take a minute and visible enough that the next person benefits.
