This is no way disregards the difficulty of living with an actually severe case of ADHD but is not what most of these people are dealing with.
EDIT: many seem to have misunderstood what I mean by this. I’m not saying these people are only claiming to have ADHD to use it as an excuse. What I mean, is that they may very well do have, and they’re using it as an excuse. Mostly to themselves.
I wonder this myself. I relate to a lot as well but I do wonder as I was that shy, introverted, bookish, nerdy kid who also spoke in class today (although when you are a target for cruel jokes is that really about something wrong with me as a kid) who evolved into a hippie type. Honestly the names have changed but I just mentioned in another post how I have not really in relation to most folks I know. Im definately always been different and hung our with folks who like that to which you found at conventions and dNd groups and anime clubs and such. Now a days those things are mainstream but at the time it was quite the nerdy thing. Remember though that harrison ford was in the AV club in high school which was the nerd club of that age.
