Reviews
The Bookseller, “Editor’s Pick,” 10/12/12 “Sensible and very readable…By far the most useful of this month’s New You offerings.”

Kirkus Reviews, 1/1/13 “Making changes does take longer than we may expect—no 30-day, 30-pounds-lighter quick fix—but by following the guidelines laid out by Dean, readers have a decent chance at establishing fulfilling, new patterns.”

Publishers Weekly, 12/10/12 “An accessible and informative guide for readers to take control of their lives.”
