Strengths
- Core advice on cues, environment and tracking lines up with peer-reviewed habit research
- Cites real studies accurately and corrects popular myths like the 21-day habit
- Flagship product is a $27 book plus a free newsletter
Weaknesses
- The thirty-seven-times claim is presented as daily 1% math, not as evidence of how people change (S2).
- Sales framing for the book is on his site and the publisher page, not an independent audit (S1 S4).
