I have severe time blindness. I’m either right on time or a few minutes before. I rely on the various scales of time available to me. Edit: to say I’m speaking exclusively to “time blindness”. Someone with full blown ADHD may have other factors interfering with their ability to utilize these tools of time measurement/management. I can’t speak to that.
Really. If you do choose to use one make sure it’s compatible with your preferred debrid service.
