Noise cancelling headphones (and fun things to listen to when doing boring stuff).
I'm another big fan of The Organised Mum Method - I subscribe to the Tom Rocks service, where she narrates me through various boring chores AND I can work out in advance how long they will take!
I pretty much stopped masking, which gave me lots more energy. My entire office (and, I suspect, a really high proportion of my workplace in general) is ND so it has worked out quite well.
Exercise is good. But it has to be fun, and also feel a teeny bit extreme. I used to do CrossFit - now that I'm old and fat I do wild swimming.
I book a day off work every three months to do all the paperwork tasks I've put off, and also book a treat at the end as a reward.
I useTile trackers on my keys, diary, wallet, handbag, and headphones to keep track of them.
I keep a bag of huel and a shaker in my office for days when I forget lunch. When I had to wear smart shoes for work, I also used to keep an old pair at work so I could get to work on time if I couldn't find my shoes.
I but multiples of things like reading glasses, lip balms etc and have them in every room, bag and coat pocket.
I used pastel highlighters when taking notes.
I write down timed routines for morning, leaving the house, leaving work, coming home from work and going to bed. I used an app called "routinery". It will then time me from my starting point and if I over-run, it lets me take time off another task to keep myself on time.
I try to meet friends at locations where there is something to while waiting so that I can be early, and they don't get too annoyed if I'm late.
I also have timed and planned routines for common social events, and try to make plans that fit into those timed routines, so I know that if I want to be at the cinema for 7 I should start leaving at ten past six, or that if I want to be at a particular bar at 9 pm, I need to leave at 8.40. it saves me from having to do all the calculations from scratch and forgetting things because I'm so focused on the timings.
If I get stuck sitting down and can't move, I've taught my family to recognise the signs. They can then tell me in a firm, commanding voice to be stand up. I can follow a simple instruction, do I stand up and that sort of resets me so I can do the things I want to do.
If I'm travelling by train or plane, I will ask for help with connections and platforms. A friend who struggles more that I do books passenger assistance for train journeys to make sure she gets on and off the right train at the right station.
I struggle going to bed if I'm too tired, so I go to bed before I get tired and read until I'm sleepy.
For a noisy mind at bedtimes, I have sleep headphones and listen to the Nothing Much Happens sleep podcasts which stop me from fidgeting and having a racing brain.
I still haven't worked out how to do financial stuff, though, so I would really welcome any money-related tips.
