Trust that resets at every new task is not trust. It is a permanent probation with good manners, and the person under it feels the shape immediately, because their record does not travel with them. Every fresh piece of work starts with proving again what was already proved last month.

With someone whose past work you can point to, begin the next thing further along than you did the last. Say out loud that you will not be watching the early stages, and then do not watch them.
