I don't believe it was flippant, and as I said, didn't intend it to be. As someone with AD/HD, and who's studied it intently for many years trying to better understand how it may affect my autistic son (who is also showing signs of AD/HD) I can safely say that the kind of procrastination he describes is exactly the kind of procrastination that manifests in someone with AD/HD. Having that kind of insight lets me help my son learn coping strategies before it's too late to make those kinds of changes to his brain in any meaningful way.

Frankly, the description you have given is very similar to AD/HD, especially the "I'm that fucking good" part. Yes, I know you weren't bragging, but that sense of infallibility and the letdown that invariably follows when your abilities don't manifest ... I'm guessing it sours you to the project you're working on? Can't seem to direct yourself back to it to care again like you did when you were focused on it the first time? Anxious to find something else that's more interesting where you can prove what a rockstar you are? That rush when you pull that rabbit out of the hat, feels good, doesn't it? Dopamine is great, when you do something that creates enough of it that your brain feels rewarded. For many, it doesn't take much. For many people with AD/HD, the last minute YOLO cramming/programming/building/working session is what it takes to feel like we're doing anything worthwhile.
