I stand by the idea proposed by Cal Newport that the best way to do great work is to do "Deep Work"—large (but not all day) amounts of no-distraction, in-the-zone work. Harder to do than ever, but when I can do it I'm amazed.
I honestly don't understand how that is different from "regular work". How else do you work if not undistracted?
"Deep work" or "flow" means there's just you and the thing you're doing, nothing else.
Maybe because I read a lot of productivity-based articles and blog posts?
One problem I did have with the book was that Deep Work might not be useful for someone whose work is largely mechanical or mundane, though in that case I'd apply Deep Work to learn skills to into more interesting jobs if one wishes.
