Pick a habit, shrink it, attach it to something you already do, and see the dates for Day 30 and Day 66 (the median in the best-known habit study).
Your Habit Recipe
Why Day 66? In a study at University College London, new daily habits took a median of 66 days to feel automatic. The book's 30 days are the launch; Part 4 takes you the rest of the way.

Good questions
Questions people ask
Does it really take 30 days to form a habit?
Not quite, and the book is honest about it. In the best-known study (Lally and colleagues, 2010), new daily habits took a median of 66 days to become automatic, with a range of 18 to 254. The 30 days are the launch: the steepest part of the climb. Part 4 takes you to day 66.
Isn't it "21 days to form a habit"?
That's a myth. It comes from a 1960 book by a plastic surgeon who said patients needed a minimum of about 21 days to get used to a change. Chapter 3 tells the whole story.
What if I miss a day?
In the research, a single missed day made no real difference. The book gives you a simple rule (never miss twice), a minimum version for bad days and a Restart Ritual.
Can I build more than one habit?
Start with one. Once it's automatic, Chapter 11 shows you how to chain the next one onto it.
What exactly do I download?
Five files: the 74-page workbook (PDF), the Habit Tracker Pack (PDF), 24 Habit Cards (PDF), a printable surprise (PDF), and a free sample you can share.
Can I print it?
Yes. Everything prints on US Letter or A4. Print the printables as often as you like for your household.
Can I see some of it first?
Yes. Download the free sample (the welcome, two chapters and two daily pages), and try the habit planner on this page.
How do I get the files after paying?
Right after checkout you come back to your SkillNugget library, and we email you a sign-in link. Download the files there any time, on any device. No password needed.
