The task might not be as bad if you can get started. I do the same thing, but if I do 5 minutes, then I forget about the drugery and now I'm in it

So tell yourself you can stop at any time but you want to be able to say that you were just working on it so you are going to do 5 min. And see if you don't decide you can do 5 more and 5 more after that...
