You can use this to your advantage to create peace of mind as I found out.

The mechanism you describe is what is the basis for the "Getting things done" framework. You learn your brain to "trust" the "authority" so it can let go of all loose ends that keep your brain busy (like stuff it needs to remember, like appointment, paying a bill, fixing something in the house, etc). But if you are able to trick your brain in not checking in with the authority (as GTD dictates) you are left with a lot of spare room in your brain to think creative, at least thats my theory.
