See the point is that you can be reasonably accomplished thanks to your talents, interests and intelligence, but let's take the very same you and remove some of the procrastination. It is reasonable to expect that it would be an even more accomplished version of you (even though you might pick up some tangentially interesting stuff that might be useful when browsing HN). To people who do not understand ADHD, your behaviour will be looked at through the lense of "if they just applied themselves...", "they are really smart but just so lazy...". That's what I mean by "unexplained underachievement". It is a useful signal for caretakers. If Johnny is so smart, then why does he end up doing everything at the last minute, inviting stress in his life that will probably shorten his lifespan by 5 years?
