Terence Tao uses a trick, I think he calls "structured procrastination": When there is a thing he doesn't want to do, he recalls another thing he doesn't want to do more. This way he's procrastinating on the other thing by doing the not favoured one.

I think that sounds like productive procrastion, it won an Ig-Nobel award. As you say, it's basically finding something you don't want to do even more than the thing you need to do, so you instead procrastinate productively by doing the needful.
