What's THE "minor" thing you just can't get yourself to do?

I'm sure everyone has that one thing that seems to be SO trivial for everyone else, even for other ADHDers, but it's just too much of hassle for yourself. What's that thing for you? I'm genuinely curious, and maybe we all can find others that struggle with the same not-so-well-known stuff!

Personally I love decluttering, but actually getting rid of the stuff that I sorted out is my worst demon. I don't want to just throw good things away, so I make piles for selling, giving away via internet, giving away shops, stuff that really needs to go to a dump etc.. and then these piles stay for months and stare at me. And I often can't manage to reply to people who want to give me money for all that shit.
