This is polar opposite of my experience. The unenjoyable ones are precisely the tasks that I will never complete unless I am very kind and forgiving to myself. Beating myself bloody with "but it has to get done" is an exercise in hopeless futility.
On a similar note, I get a lot of "chore" tasks done by basically just being impulsive about them: if I have a free 15 minutes before a meeting or after breakfast or whatever and I'm feeling high-energy I'll just pick something off my long household to-do list and do it then. The results aren't all that consistent but everything gets stochastically done eventually.
