I didn't think of that! Do average people commonly feel an inner disquiet over the fact they lack skills, or is the quote saying that learning skills will help with the vague mental unwellness people might have but don't know why? For the most part I've always known, or at least thought Ive known, Why I'm Miserable, and the only skills that have a part in it are math and driving a car, and a few highly specialist things I wish I'd learned, like going into industrial controls. I do know people who are uncomfortable being a specialist that couldn't function without industrial society as we know it, but the quote seems to paint it as a universal thing.
