Much more personal than Dune. Smaller in scale.
The Jihad as Paul experienced it — trying to escape it, trying to protect his family — is the heart of the book and it works. What's missing is the Jihad's effect on the universe. The race consciousness unleashed, the actual cost. We hear about it but never see it. Maybe that comes later in the series.
Most of it felt obvious. Small changes compound. Systems matter more than goals. Habits have cues, cravings, responses, rewards. If you've thought about this at all, you've probably already arrived at most of it.
The first half is still worth reading. The implementation intention framing — "I will do X in location Y at time Z" — is specific enough to actually use. I applied it the same day. "After making coffee → meditate in the living room." The morning negotiation I'd been having with myself for weeks just disappeared.
The second half is the same four laws applied to different examples. You can skim it.
Worth it for the first half alone.
