ADHD here. Remembering things is a lost cause for me.
Instead, I lay physical “traps” for myself. Things in physical space that hinder my autopilot, snap me out of the trance, and give me a chance to reorient my focus into something more productive.
It’s not foolproof. Far from it. But it does help a lot.
Edit:
Just thought of another one I do: I have a phone casing that lets me keep cards in them. One of my credit cards go there, of course.
But the more important thing in there is my apartment access card. If I ever forget to bring my phone, I will only get as far as the security door outside before I realise I have to turn back.
I wish this worked for me. I’ve put things on the doorknob of my bedroom and still forgotten to take them out of the house. Setting reminders on my phone works though for some reason
I am soo blind to phone reminders. I have one go off every day telling me what to take to work and it’s just a thing that exists that I jus switch off daily without thinking. Can’t even be bothered to remove it.
My plan A – tie the lanyard of my keys to whatever I need to take with me.
B – Walk out and put it in the car the night before. Interestingly, this is the most annoying to actually do, but I have never regretted it afterward.
