Definitely pinching the spreadsheet match to Tesco (or wherever) idea - that is truly genius!
I think people have already said lots of things I would have, about laundry/ironing (our local laundrette does masses of service washes and has recently adding ironing, although my favourite ironing minimising trick, borrowed from a friend who always looks immaculate, is to be there with a bunch of hangers as the wash comes to an end and hang things up instantly), getting a gardener, regular handyman, housekeeper, etc.
And others have also mentioned making use of calendar reminders etc, mine tend to go into my gmail AND my Teams at the same time, so one keeps me on track with home stuff and the other with work (okay, sometimes there's a crossover).
The other thing I do is write down at the end of each day a set of tasks that I know I need to do the next day and email them to myself, then that's what I start with the next day. Obviously some things end up getting carried over, but I've found it really helpful to keep on track.
I also have weekly/monthly/quarterly/annual things I know I need to do that I stick on a physical calendar as well as online - recycling/rubbish; cleaning the fridge and chucking out gone-off food; clearout of clothes and broken items beyond repair; sorting the car MoT out - and that way nothing from that group of tasks comes as too much of a shock, and then I have a bit of headspace to deal with the more unexpected life things.
And then there are my bright red "To Do" folder which has urgent bills etc in and I go through once a day, and my "Filing" folder, which is where I stick things that I've done from the "To Do" folder until I manage to file them...
The bane of my life is the sorting box, though, which is variously sized depending on what's going on, and can have anything in it from random phone leads to the cat's current bag of Dreamies...
A friend has just started having a cleaner in a couple of hours a week and says it's making a huge difference, although they don't have kids she and her husband have incredibly busy jobs.
