In exactly the way the author claims, this book has really helped me improve my life over the last 12 months. The strength of this book is its powerful simplicity. Many of the ideas, suggestions and techniques can be found elsewhere in many other popular self-help writings, but Jinny Ditzler's approach inspires action almost effortlessly. Compared to other similar books, it is almost impossible to read this without making at least one or two of her lists which then empowers you to make positive life changes.
A criticism might be that it is fairly basic stuff that we know already, but answering the various lists of questions here brings new clarity and confidence about what is going on, or not going on, in one's life. Parts one and two are preparation for "the ten best year yet questions" in part three. These are basically all about looking honestly at your life, seeing clearly what works and what doesn't, then setting clear and specific goals in different areas over the next 12 months.
If, like me, you are someone who loves reading these kind of books but finds that it often seems to take rather a lot of hard work to put the ideas into practice, I recommend Your Best Year Yet! Inevitably I did not achieve some of my goals for the last 12 months, but the considerable improvements I did make (plus increased clarity about goals for the future) were partly due to getting a realistic focus from this book.
