Nothing like having to constantly remind yourself about things so you don’t forget, even little things like transcribing a measurement or something, or sit immobilized over a pending event because you don’t want to do anything that might distract you from engaging in said thing. Having to re-read things several times to keep it in short term memory and then having to check that yes, indeed, you did it right, and then check a couple more times to remember that yes, you did check it, and it’s still right.
