I’m a list person, but these days it’s all electronic.
I’ve set up my Calendar App on my phone to send me reminders a week ahead of things like doctors appointments, birthdays, social things to which I’ve RSVP’d.
My Notes App is where I keep my own to do list plus various other lists….projects or research for clients for example, or recipes to try, etc
We are a wish-list family, so Christmas and birthdays the refrain is always “need your list!”
I have an App for groceries which keeps a running tally of all the groceries I’ve added, by category, and the touch of a button allows me to edit that list to view only the things I need that week.
I keep a hard-copy list of Ron’s Honey-Dos, and we both add to it as things come up, and mark them done when we’ve finished them. It’s just a spiral bound notebook that sits in the laundry room, and he also keep notes in there if he needs to remember measurements for wood cuts or dimensions for a project. If he needs that info to take to the store he just takes of photo with his phone of the relevant info or page, because like me, his phone goes where he goes.
