How about trying to actually do it? I agree self-help books are mostly fluff that can be said in half the length, but I do think "Deep Work" is a useful technique.

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.

Maybe it doesn't teach anything new, but it does act as a refresher and makes you go back to Deep Work. I had almost completely forgotten about it and my work schedule was full of tab switching and short breaks. After going through the book, I started using Toggl and minding my time.

Then pass it in to your boss. That's what I'm going to do, now that I'm finished with it.
