I have a written routine. But life seems to not agree with it. There is a disconnect between what happens, and what I say I want as routine.
However, the written routine is still a big help. There are times after a work-blitz that I really don't know where to begin with getting things done. I just look at the routine, and dig in.
It's a detailed routine, though. "Clean office" is just too general. I have filling the paper trays in the printers, dusting, cleaning windows, vacuuming, decluttering bookshelves, filing, tax work, and other things broken out separately.
Ditto with the rest of the home.
