Even though I've not been diagnosed with ADHD or any other attention disorder, I've experienced what you call "hyperfocusing" before. My conclusion is that more measured focusing "feels" more genuinely productive in the long run as it lets you get additional things done too; the problem is getting more measured focus on intriguing projects that prompt hyperfocusing in the first place. I never got the hang of it myself, lest I lead you to believe I've found a solution.

Additionally, people capable of surviving without any sort of social interaction seem few and far between, and these recluses that I've met still cheat by conversing with their cats. Hell, even I end up talking to my parents' cat when I have to spend a weekend alone with him.

My mental problem, as I mentioned previously, is perfectionism, and all the while I am writing this, my inner cynic is coolly pointing out that I'm most likely sitting here writing as a way to avoid doing something more productive that I've already convinced myself I cannot complete satisfactorily. What is it that all those twelve step programs say? Identifying and admitting to a problem is the first step to solving it? Unproductive Indiviuals Anonymous anyone?
