I have ADD. Not ADHD; I'm almost never hyperactive. I do, however, hyperfocus on anything and everything, to the point that it's caused severe problems to my career, relationships, and personal life. I'm nearly always hyperfocused on something, and I rarely have control over what that is. I'll forget to eat, sleep, talk to people, or really do anything else for several days at a time when it gets bad. Fortunately, over the years I've learned techniques to solve some of the problems, like having somebody to hold me accountable. Even so, it remains my biggest challenge.

However, it's also one of my greatest strengths. When my brain decides to attack a problem, I'm astonishingly productive. Over the last couple of weeks, I've been hyperfocused on implementing a motion control system for a side project. As a result, I've designed a CoreXY platform, designed a control board for it, learned how to use ngspice to tune the power-up circuit, learned how to use Sympy, used it to derive closed-form solutions for jerk-controlled motion, and found a way to implement that solution in which the motion control interrupt takes a grand total of 70 cycles on Cortex M0. And this is just my spare time outside of work, where I had a completely different set of hyperfocii, and similar productivity.

So, I completely agree with the author that if somebody were to offer me a megadollar in exchange for getting rid of my ADD, I'd have to think very hard about that indeed.
