Orchestras tune to one note from the oboe before every concert. Be the steady note people can tune to.

A group needs one reference point that does not move, or everybody tunes to each other and the whole thing drifts. Being that steady note is less about being right than about being consistent, since what people need from you is something to measure against. A reference that wobbles is worse than none at all.

Pick the few things you will be utterly predictable about, whether that is arriving on time, your tone when things go wrong, or how you treat people who are behind. Hold them even on a bad week. People will set themselves by it without mentioning it.
