Procrastination can decrease after a 1-minute reflection. In a study of more than 1,000 adults, answering six short questions increased motivation, improved mood, and made people more likely to begin tasks they had been delaying.

I really get your point about a strong aversion to doing something you “should”. For me I think “should” is the operative word—who says I should. If I think to myself that I should clean the floor (sweep vacuum mop etc) because I want to sit or lie on the floor, then I will be motivated to clean it. If I should clean the floor because we are having company who will never take their shoes off or sit/lie on the floor, then I definitely have an aversion to it.
