"Disorder," at its most basic, simply describes a lack of order, which is not the same thing as a congenital disease. These days, we tend to over-identify with a given diagnosis, as if it were a permanent condition. People talk about their ADHD diagnosis as if it were a fact as permanent about them as their eye color. And for those that have struggled with ADHD their whole lives, it can certainty feel permanent. But if your room's in disorder, you _can_ tidy it up—, even if it takes you all year. "Disorder" in this sense is a description of state, rather than an inherent property.

Furthermore, the attention which is in disorder with ADHD is a skill which can be acquired. You can train your attention like you train a muscle. There's a real proliferation, these days, of medical and chemical treatments for ADHD. And many of them really help people. But if your goal is to build muscle, maybe what you need isn't a steroid injection, but an exercise. Some of the best ways to train one's attention are the oldest. Zen Buddhism, for example, has been around for fifteen hundred years or so, and has a lot of evidence behind it. If you sit in zazen for a full sesshin, at around ten hours a day for a week or two, you will undoubtedly start to develop strong powers of attention. But even ten minutes a day is effective. Hard work, daily, at training your attention, _will_ turn disorder into order.
