1. Remember to keep a list
2. Remember to update the list
3. Remember to check the list
4. Start a new list because I can't remember if / why I care about anything on the old list
(Personally, I've never started a list but I can imagine how it would go.)
On balance, this shift in my attitude means I definitely use more simple organizational tools more often than I did in the past, and that has certainly helped my productivity.
* Christmas / birthday ideas
* House TODO
* Project ideas
* Car maintenance
I'm always writing emails, and I notice that I've got things in my drafts folder, so it reminds me to keep it updated.
That said, gaining those skill and having treatment feels like a superpower
Treatment - whether medication or otherwise - will help you to focus, but it won't magically teach you organization, time management, note-taking, active listening, etc.
I was incredibly lucky, once I got into software dev, that my untreated ADHD often manifested in hyperfocus, so I could deliver large amounts of business value in bursts, that meant my other foibles were tolerable.
Of course, my spending 20 hours of a day hacking on something for a week was very hard on my family, but at least I stay employed.
I much prefer being medicated. The symptoms are still there, but manageable. I still need lists to ensure I don't forget things, but at least with medication I a) remember I have a list and b) remember to use it.
So many times previously, people would say "Just write a list, how hard is that?"
It was quite hard.
