I'm diagnosed ADHD, too.
My luck is that I have a loving wife who helps me. It would be far more difficult without her, but I guess I would have to use checklists if I had to do this on my own.
I should've said that I've been ADHD since my early 20s and have been coping for over 30 years.
Or maybe it should have been obvious by the specificity of my advice.
