you can be very smart and still have the condition  yep i was always able to keep pushing through i did really well in grade school i pretty much did 4th and 5th grade in my 4th grade year i was tested in high school because they thought i needed remedial help their testing said i was very smart but bored i eventually got through high school i did very well in college usually having the highest marks on exams even though i rarely showed up for class people assumed me included that it was because i was learning things i wanted to learn finished college and i was always able to hold down jobs afterward moved quickly up the ladder in my mid 20s and was expected to keep moving higher i had some ups and downs - anxiety problems and so on in hindsight they were adhd related so i never really went as high as anyone expected and eventually burned bridges and bounced around a couple of different jobs   the anxiety and depression built up like a time bomb that went off in my early 40s i finally got so bad that people who cared about me made me get help i spent a couple years getting out of a decade long bout of chronic depression only to realize i was still having a lot of the problems that were always blamed on my ever increasing anxiety and depression i also happened to be working with someone to have my child diagnosed so as i was going through that alarms bells were going off because she was exactly the same as i was at her age  now im kind of back at square one waiting to get a proper diagnosis i can at the very least start learning about how to deal with it now because i know whats different about me but i really wish someone figured this out 20-30 years ago   sorry for the wall of words tldr - undiagnosed adhd is terrible
