Doubt is a notification. You don’t have to open it.

A doubt arriving is not the same as a doubt being correct. It shows up like an alert, demanding attention and implying urgency, and most of them contain nothing you did not already know. Treating every one as requiring a full response is how an ordinary afternoon turns into four hours of arguing with yourself.

Let one go by unopened this week. Notice it, name it as doubt, and carry on with whatever you were doing. You can come back to it later if it is still there, and usually it will not be.
