I do not know much or anything about your situation, but here is one thing that might work.

I would suggest picking a fixed point in time every week. At this point in time you will finish (if they are small enough, otherwise split in multiple steps) on of these chores/repairs. E.g., every Saturday afternoon from 1 am you will finish one of these. The rest of the time you then do not need to think about these which is your reward for doing one chore/repair.

Everyday I have to prepare dinner and put the plates, glasses, forks and knifes in the table, and, I don't know why, get that feeling that I'd rather do anything else (or, most times, nothing at all). So I always start everything by putting the towel in the table (don't know if it's called like that in EN, not a native speaker). It seems to click something and the rest follows.

Maybe the idea can help you starting things?

It also helps that, sometimes, when the tasks are big, I convince myself that I can finish it later. Many times I do not have to finish it later..
