Don't go for 100% completion. You are doing a laborious, repetitive task you don't enjoy that doesn't accomplish or create anything, in order to bring an integer up to its triple digit.
There is a reason completionists and speedrunners tend to troon out. They are insane people who have a nagging voice in their head that makes them feel like a lesser person if they don't go for 100% completion. Tell that voice to fuck off, and don't go for 100% completion, and then do something fulfilling with the limited amount of time you have on this gay earth.
