If I don't know there's a task, I try to remember, and when that fails, I rationalize it can't be that important or I'd remember it.

60% chance I feel the crushing weight anyway. 30% chance it was REALLY REALLY important, so I feel the crushing weight later as guilt. 10% chance I feel the weight anyway AND it was really important.

Once though, once there wasn't anything important and it worked. Great day, would have again. Fresh out of those unfortunately.
