@panickyintheuk have you ever looked into bullet journals? mine was kinda life-changing lol. a good agenda is a key component to managing ADHD. daily to-do lists are my other big thing - write out every single thing I need or want to do, including leisure/hobby stuff, and how long it'll take. it REALLY helps keep me on track so I don't wind up getting lost in the internet and losing my whole evening on things I don't even really enjoy.
