You got trusted the day you fixed a mistake nobody would’ve caught.

Trust tends to form in private. When you repair something that would never have been traced back to you, you show that your standards do not depend on being watched. People sense that even when they cannot point to the moment it happened. It is the difference between behaving well and being dependable.

Next time you spot your own small error, fix it before working out whether anyone noticed. Mention it afterwards or do not; the point is the habit rather than the credit. Keep that up and you stop needing supervision.
