There are still people with (varying degrees of) ADHD that are both normally successful or wildly successful. They did this likely not despite their ADHD but because of it. They probably grew up in an environment that allowed them to find a positive outlet for themselves so they achieved behavioral patterns that utilized it to drive them forward instead of it getting in the way.

Yeh people with ADHD could just educate their parents and teachers about how their brains work differently

getting my parent to believe [evil food] poisons me took almost a decade and they had explicit proof.
