I don't think that's the point of this article. The real point is that you learn through actually doing stuff. You can read as many books as you want about designing your medical equipment, but I can be pretty much anything that you won't get it right the first time anyway. So read just as much as you need to get you started, get to real work, and soon you'll find out what else you have to read about. And so on and so on. Try, fail, educate yourself, repeat. With your to do app release after 3-4 iterations, with medical equipment release after 30-40. But keep on trying and actually doing, vs meditating about it. This is how I see this article, and therefore it applies to both, to-do apps and more serious stuff.
