Yes, usually, we see pointing our weaknesses and we are advised to work to eliminate them. However, as this book shows, it is more interesting to work on our strengths. This is done much more naturally and is much more rewarding. The author gives the example of Michael Jordan that failed when it started golf. It was nice to work like crazy, he could never reach the required level. But with predisposition for basketball, it has developed its core competency in this area and become the champion is known. The book is in English but the test can be taken in French. Results are in English. I recommend this book to all those who want to build on their strengths and develop them.
