I'd add to this excellent suggestion which has worked for me: If we complete things that are not on the list, go note it on the list even though you've done it. I get frustrated whenever I end up doing things that are not on my list which throws everything out of kilter and I stop doing my list ... which is a disaster. So I found that I feel better whenever I add a completed item to my list. :-) The lengths we go to trick our mind.
