I’ve seen this several times before on the internet over the years attributed to a few different people. Most recently I found it here. But I thought I’d grab it and save it in case it ever goes away and also to remove most of the annoying adds that other sites seem to surround it with.
ADHD is about having broken filters on your perception.
Normal people have a sort of mental secretary that takes the 99% of irrelevant crap that crosses their mind, and simply deletes it before they become consciously aware of it. As such, their mental workspace is like a huge clean whiteboard, ready to hold and organize useful information.
ADHD people… have no such luxury. Every single thing that comes in the front door gets written directly on the whiteboard in bold, underlined red letters, no matter what it is, and no matter what has to be erased in order for it to fit.
As such, if we’re in the middle of some particularly important mental task, and our eye should happen to light upon… a doorknob, for instance, it’s like someone burst into the room, clad in pink feathers and heralded by trumpets, screaming HEY LOOK EVERYONE, IT’S A DOORKNOB! LOOK AT IT! LOOK! IT OPENS THE DOOR IF YOU TURN IT! ISN’T THAT NEAT? I WONDER HOW THAT ACTUALLY WORKS DO YOU SUPPOSE THERE’S A CAM OR WHAT? MAYBE ITS SOME KIND OF SPRING WINCH AFFAIR ALTHOUGH THAT SEEMS KIND OF UNWORKABLE.
It’s like living in a soft rain of post-it notes.
This happens every single waking moment, and we have to manually examine each thought, check for relevance, and try desperately to remember what the thing was we were thinking before it came along, if not. Most often we forget, and if we aren’t caught up in the intricacies of doorknob engineering, we cast wildly about for context, trying to guess what the hell we were up to from the clues available.
On the other hand, we’re extremely good at working out the context of random remarks, as we’re effectively doing that all the time anyway.
We rely heavily on routine, and 90% of the time get by on autopilot. You can’t get distracted from a sufficiently ingrained habit, no matter what useless crap is going on inside your head… unless someone goes and actually disrupts your routine. I’ve actually been distracted out of taking my lunch to work, on several occasions, by my wife reminding me to take my lunch to work. What the? Who? Oh, yeah, will do. Where was I? um… briefcase! Got it. Now keys.. okay, see you honey!
Also, there’s a diminishing-returns thing going on when trying to concentrate on what you might call a non-interactive task. Entering a big block of numbers into a spreadsheet, for instance. Keeping focused on the task takes exponentially more effort each minute, for less and less result. If you’ve ever held a brick out at arm’s length for an extended period, you’ll know the feeling. That’s why the internet, for instance, is like crack to us – it’s a non-stop influx of constantly-new things, so we can flick from one to the next after only seconds. Its better/worse than pistachios.
The exception to this is a thing we get called hyper focus. Occasionally, when something just clicks with us, we can get ridiculously deeply drawn into it, and NOTHING can distract us. We’ve locked our metaphorical office door, and we’re not coming out for anything short of a tornado.
Medication takes the edge off. It reduces the input, it tones down the fluster, it makes it easier to ignore trivial stuff, and it increases the maximum focus-time. Imagine steadicam for your skull. It also happens to make my vision go a little weird and loomy occasionally, and can reduce appetite a bit.
Hope this helps and please do share this so that more people can learn what its really like to have ADHD.
