Unsolicited life advice:
The amount of cognitive effort to be human has been increasing dramatically.
Lean into old people stuff. Get a day-of-the-week pill box so you don't have to remember any of that. Live off to-do lists. Put reminders for every damn thing in your phone. (One of the few good uses of talking to your phone.) Sticky notes everywhere, etc, etc.
There is no need to remember most of this stuff. Get it out of your brain so your brain can brain more.
