Deep work was really helpful. This one is a disappointment. After reading 30 pages found myself skipping, after 50 pages I gave up. This book was a drag, no real substance, even the case studies and stories seemed irrelevant and off topic most of the times. If you've read deep work and watched some of calports videos, skip this. The book had like 50% content and 50% reference pages. There was no concept, idea, or actionable steps. You already know all, I bought it so I could relate to case studies but even those were off topic. So not worth it.
