What's one small thing you've done to make your life easier?
For example, I 3d printed a box over my outlet to protect my cables from my bed pushing against it. In addition, my cables never fall to the floor so they're much easier to grab.
Set calendar alerts for routine tasks that need to be done less frequently than once a week.
Things like washing the vacuum cleaner filters, descaling the kettle, replacing the water filter (I'm in a hard-water area), servicing various appliances, cleaning all the things that need cleaning but don't need cleaning every week. All small things. It removes a lot of cognitive effort and makes sure those things actually get done.
This is a big one. I try to tell my ADHD teen he needs to do this because he is constantly forgetting to do things (feed his cat, pickup around his room, go out to the school bus in the morning). He's very oppositional to change and doesn't think it'll help, even though he's either on his phone or PC all day long.
