I have a post-it note in my desk drawer that reads "Don't Prioritize, Just Keep Moving".
With ADHD, executive function is a challenge, and the moment I try to slow down and actually plan out an entire day or I try to force myself to do that one thing, my brain has a tendency to just shut down. The way I get things done is just by doing the next thing my brain latches onto.
Is this ideal? Of course not. But fortunately it (usually) works reasonably well for my job, and the alternative involves being more stressed and getting less done. That's not to say I don't prioritize at all, but I try not to let it get in the way of my flow.
