About the 30-day email course
According to the site, the course walks you through the first 30 days of a habit step-by-step, includes a 20-page PDF workbook with templates and cheatsheets, and adds examples not found in the book. It is described as usable for any habit — from getting fit to saving for early retirement to daily meditation. The site says you receive one short email every three days for a month and can unsubscribe at any time.
How to decide if it fits you
- Choose it if you want a structured, small-changes approach to habit formation and a widely read, mainstream entry point to the topic.
- Consider the free email course first if you want to sample the framework before committing to the book.
- Look elsewhere if you want clinical, academic, or deeply research-cited treatment — the site positions the book as practical self-improvement, not a scholarly text.
