Making the plan in the first place is difficult for a lot of people. Following the plan can be orders of magnitude more difficult, particularly if someone is entrenched in a routine.
Making a plan is effort, but you can make the plan as easy as possible. My plan for home living is to have zero chores throughout the week. Only one day a week I will do chores, and it'll be 1 hour (2 hours if I have animals). Imagine coming home from work and having absolutely nothing to do, so horrible ugh I should be cooking, cleaning, and grocery shopping until it's time for me to leave for work. Having time to unwind, shower, and sleep is for tech bros 🙄
My view is that the perceived difficulty of changing your life is greater than the perceived simpleness of the current process.
Maybe there is some brilliant way to automate my most tedious chores. But then I've got to spend cognitive power directed at a task I find tedious. It might be easier to do things the way they've always been done rather than to think and try out new processes which don't always work.
Spend cognitive power once. Then "never" do it again. I'm never mopping, vacuuming, grocery shopping, or washing dishes. If I have animals I'm never feeding them, giving water, cleaning waste, grooming, or bathing them. All of that can be automated, so I'm automating it. Am I really going to spend my limited time on earth cleaning up dogshit?
Life is pretty hard though, and you can't change everything. I don't know if that means you shouldn't try, but I understand someone's desire to keep their head down
You could change a LOT. For starters, you really don't need to drive to Costco for groceries. You could spend those hours doing something much better for yourself instead of going into traffic to complain about the traffic, walking in a crowded store to complain about the crowded store, wait on a long line to complain about the long line, then load up the car while hopefully not being screamed at by some tiktoker about putting the cart away, then drive home in the same slow traffic that can be lapped by a toddler on a three wheel scooter going up a hill, then unload the groceries for an hour and spend more hours trying to fit it all into the overfilled refrigerator and freezer you didn't check before leaving, and then finally checking the time to see that you will be late for work if you don't rush and get dressed and leave in the next twenty minutes. That actually can change, and whatever extra costs are probably as high as the amount you spend on gas, car insurance, Costco membership, anti stress supplements, weed, and impulse purchases made to cope with having to pull all nighters every weekend. You could just, not, pull all nighters for one fucking chore.
