I reject both "D"s in ADHD. I find it neither a deficiency nor a disorder. One of the most rational papers I've read on the subject noted the necessary evolutionary differences between humans in an agrarian society and those nomadic hunter-gatherer type situations. Each requires different skill sets. What we call "attention deficit" can be an asset when hunting - where the hunter can become another animals prey. The ability to shift attention rapidly can mean the difference between eating and being eaten. The ability to do repetitive, even tedious tasks with concentration is essential to successful farming and ranching. This analysis made a lot of sense.

As one with a short tolerance for repetitive and tedious - what my generation called "short attention span" - I've turned this to my advantage. I'm would not survive as a farmer, but as a musician and technologist seeking always to learn something new, my nature can be an asset rather than a deficit.

The disorder is the need to view anything outside of some arbitrary "norm" or substantially different as deficient...in my opinion ;-).
