When I was looking at a questionnaire about ADHD I showed out to my wife saying something like “man, they’re really gearing these questions to diagnose everyone with ADHD, aren’t they?” She read through the list and then, with the saddest expression I’ve ever seen on her face, looked at me and asked “you mean you’ve been struggling with all of this?”

Getting diagnosed was a formality after that.

For real. The concept of becoming a master over a wand is world breaking in retrospect. Ron talks about using a hand-me-down wand in the first book, which basically means he was hampered from the beginning by not having a wand that recognized him as its master. And all the wand disarming Harry did means he should have approximately 37 wands that prefer him over their owners.
