I talked about this on
@Crankenstein's thread, it's something I have gradually found strategies for, over time, and also refined my strategies. Mostly these come down to planning ahead, for me, and lists. I use a paper diary, which ends up looking a creative mess, but if a page gets too full I stick a post it over it and continue.
I break down tasks into chunks, and allocate time to tasks. I do sometimes unfortunately completely forget a task, but not usually for so long that it's a problem. On the whole, I list tasks or have them in my diary. I also use my email as a store and can find relevant emails by date or sender.
I redo the lists daily at times, or whenever I need to update them. It helps me focus, and be realistic about how much time I have and prioritise how to use it.
Executive function issues also relate to getting around, I find it hard to leave home with everything I need, so yes, I make lists and often pack my bag ahead of time. I plan journeys, like, tomorrow I get my second covid jab, so I have planned my route and timings. It's the same venue as the first hurrah, as finding my way around new venues is often a magical mystery tour.
But the guys organising that venue seem awesomely good at anticipating confusion, there was a person pointing the way at every junction of corridors. I also can't anticipate easily what I am supposed to do , so I waited for directions there, which were given, but often in a strange building there's no one and I get stuck or lost. I don't mind it, it's quite funny sometimes. But it can be time consuming. I mostly just work to keep calm and lighthearted, as I roam the corridors etc. I'll know for next time...
This is also why I enjoy walking with people who know their way already. That's my best strategy for finding my way.
