> ADHD doesn't necessarily present as "hyperactive child" or the other stereotypes to which it often gets associated. Many people receive an ADHD diagnosis in adulthood after years of (more or less) successfully coping by employing organizational strategies.

That's pretty much been my case so far :') (though yet undiagnosed, only suspected).

It's not necessary to know that you have ADD/ADHD to tackle these issues, but it gives you a good idea of what's going on.
