The fact that you can't remember an agreement you made with yourself doesn't mean that you're not holding yourself liable for it. Ask any psychologist how much of a sense of past and future that part of your psyche has, the part that was storing the list you dumped: zero. It's all present tense in there. That means that as soon as you tell yourself that you should do something, if you file it only in your short-term memory, that part of you thinks you should be doing it all the time. And that means that as soon as you've given yourself two things to do, and filed them only in your head, you've created instant and automatic stress and failure, because you can't do them both at once, and that (apparently significant) part of your psyche will continue to hold you accountable.
