For me, it was fantastically depressing: basically it says: “OK, so you have ADHD. Sucks to be you. Go through this huge laundry list of these and those things to do, don’t forget to take your medication, find a mentor — assuming anybody would want to deal with you, and who could blame them? — and if you are extremely lucky, and with heavy effort, maybe you can become half a normal man or woman who runs through all of this effortlessly, which you’ll never be. What a burden to society!”
All of this is true perhaps, but now I just want to die.
It's a cliché, but comparing yourself to others is a bad idea in this domain. I have yet to meet an ADHDer who makes these sorts of "upward comparisons" and derives anything useful from them; they typically just exacerbate feelings of inadequacy and hopelessness.
Personally, I know I might never be as effective or productive as a person without ADHD is capable of being, but I can be the best version of myself — it's fruitless and unhealthy to ask more of yourself than this, right?
