I have severe ADHD, but these habits are some of the ones that I've managed to stick with.
I plan meals a week at a time. They're printed out on as a pretty menu and stuck on the kitchen wall - no extra work but makes me 😊. Plenty of last minute changes each week, but it makes life so much easier!
My children and I have clothes put out ready every night before going to bed. And bags packed or semi-packed. It seems to take less time in the evening than in the morning.
I have a tiny appointments diary to keep with me when I go out, and a giant A4 planner. Every Saturday I plan the week to come. Everything gets written in the planner including the time I need to leave the house for things, and therefore the time I need to start getting us all ready. And including food prep for the next day. I am more punctual and less forgetful than than ever before in my life.
I habitually make extra food and freeze in containers bought to fit my freezer well, so I can stack 9 meals for our family of 5 in each drawer. I couldn't afford that many containers, so once meals are frozen I briefly take them out of the freezer to remove, wrap and label them.
I put on a load of laundry, hang up a load of laundry, take down a load of laundry, and sort and put away a load of laundry every day except Sunday. Quite often two loads (young children, and 1.5 in nappies), but always one. Then it's never an intimidating job.
I am trying to turn my house from a hoarder's hideout to a place of order, calm and beauty 🤣. Every night (except Sunday) I try to get each room as tidy as it was before, and then try to do one thing to improve the house/organization/etc. So I still have chaotic drawers and even some chaotic rooms, but I'm making progress every day which is so psychologically helpful!
I try to ask myself for a number of meals and other activities each day "could I do this outside instead?". Healthier for us all.
Whenever I leave a room I try to take an item in the right direction towards it's home, even if that isn't all the way.
When I'm on the phone, I never sit. I gently potter and tidy.
When I walk into a room where my husband is, I usually touch him. And when I need to chat to him, I'll cuddle him. I know that would drive some people mad, but it makes him feel more loved and happier and is easy for me to do.
I stand on one leg to brush my teeth. And I do pelvic floor exercises when first in the car. Meant to make a habit of both for years and never managed it until I habit stacked it.
