I live in France and wanted to learn more about the country. What better way than learning about its people. Luxury makes top ten French exports. And when you say luxury in France, and pretty much globaly, the name of Coco Chanel will pop up. She is also a woman of exceptional success, an additional reason to learn a bit about the whys and hows. Pity the ghosted memoirs commissioned by Mademoiselle Chanel were never completed or published. So will have to rely on others telling her story. 
This book is presented as a biography but also as a self-help book, an aspect I overlooked at the beginning. But if you want it, the life lessons might be a bonus. Especially, as the author tries to make it fun and easy to digest. The book is a pick into Coco’s rich life, written around 12 life lessons or rather some of her phrases and quotes. 

It was a good reading as it rose many other questions i want to further explore for professional purposes. I will next go for some of books recommended here http://www.telegraph.co.uk/culture/books/bookreviews/8838863/Coco-Chanel-Five-books-about-the-fashion-designer-review.html.
