Preface to the Second Edition

When I first considered publishing an update to the first edition of my book INSPIRED, I estimated that maybe I would modify something like 10–20 percent of the content. That's because there was very little of the first edition that I wished I could change.

However, once I got started, I quickly realized that this second edition would require a complete rewrite. Not because I regretted what I had written, but because I believe I have much better ways of explaining these topics now.

I had no idea that the first edition would be as successful as it has been. Thanks to the book, I have made friends all over the globe. The book has been translated into several languages, and despite being nearly 10 years old as of this writing, sales continues to grow, all by word of mouth and reviews.

So, if you have read the first edition, I thank you, and hope you enjoy the second edition even more. If you are new to INSPIRED, I am hoping this new edition accomplishes its objective even better.
