I don’t. Nobody does. When you’re an adult, your to-do list never ends. It’s no longer just a couple of chores before dinner. It’s literally a never-ending barrage of cleaning, scheduling, cooking, working, tidying, repairing, caring, planning, etc. By the time you’ve cleaned the kitchen and exercised and called your mother, the cats need a vet visit scheduled. When you get home from work, your kids have emotional needs and you’ve got to get the car in for its checkup while planning dinner. You forgot to get your flu vaccine, you’re out of laundry detergent, and you still need to get a present for your sister’s birthday. As you’re taking the trash out, your boss messages asking you to cover an extra shift on the weekend. You agree, but now need to ask the neighbor’s teenager to mow your lawn and schedule a playdate for your youngest. Meanwhile, the sink got clogged and there’s a fresh bill to pay. By the time you’ve changed the lightbulb in the pantry and thrown out the mouldy pumpkin left over from Halloween, it is high time to clean the kitchen again. And after you’ve signed the kid’s permission slip and packed lunches, it’s midnight and you go to bed feeling bad that you haven’t vacuumed the den.
Seriously. Unless you’re lucky(?) enough to live with your mother, adult life can be very difficult if you think of it as “getting everything done”. Instead, try to remember your values and priorities. You only have a limited amount of time, and to protect yourself from burnout, you need to spend a fair amount of it resting and sleeping.
I don’t mean to imply that life as a kid or teenager is easy or simple. I think kids are under a lot of pressure to perform. When I was in high school, I was chronically sleep-deprived and had very little time to enjoy myself. So it is very possible that your to-do list is already endless. Especially if it involves care tasks like checking in on relatives or friends.
