Arrogance always gets invoiced eventually. Usually at the worst possible time.

Acting like you cannot be wrong works right up until the moment you are, and by then you have removed every person who might have warned you. The bill is rarely a dramatic fall. It is the help that does not arrive, the heads-up nobody bothers to give, the second chance that goes to somebody easier to root for.

Watch for the moment you stop asking questions in a room where you are the most experienced person. That is where it starts. Ask one anyway, and mean it.
