I saw this book in stores several times before finally buying it. It turned out to be a very worthwhile read.
The subtitle of the book is "Discovering What to Do with Your Life". That is a good summary of what the book is about, but may not mean what many might think. The book's message is about finding and carrying out one's unique mission from God. There are many illustrations of the points made using examples from the lives of real people, many of whom are well known.
The book may seem a bit too "fundamentalist" to some, but I say to them, look beyond that. This book has a lot to offer. I think I may have found my mission while reading it or at least the right direction to head in in this regard. Maybe you will too. Give it a try.
At least in the edition that I read, there is a code inside the front cover that allows a reader to get a personality profile and spiritual gifts analysis for free online. I found mine quite enlightening. A great added bonus!
Wishing you the same good luck I had with it.
