Absolutely, categorically wrong. There's plenty of literature on the subject, should you wish to correct your assumptions.

For those with serious symptoms, medication can help make it possible to use coping strategies. It doesn't make it easier, just possible.

To put it another way we'll never be neurotypical (normal), and if that's your expectation for someone with ADHD, that's not our problem.
