There's different degrees of ADHD, like in my case I don't have hyperactivity though I have issues completing things I'm not into, however if it's something I am passionate about, I'm 110% in on it.
I have 19 hrs towards my private license, have flown 3 different lines of planes (Cirrus, Cessna, Piper), have a great understanding of aviation principles and aerospace science, and am confident I can operate in every class of airspace proficiently.
