"There is no universally accepted measure of what success is". This encompasses the basic point which is potrayed in this book.
The author is not a writer thats quite apparent when you start off the book.
The book starts off with the author trying to pull in the readers with narrating stories of a person who he calls as "PLUs"/ People Like Us. The problem however is that you quickly learn that the person he speaks about is not a PLU at all and has had extraordinary opportinties in his life. Yet he continues to drone on about this PLU for about half of the book (Literally, for about 80 pages). This part you'll have to wade through & read. But once the author gets out of his own way and start wrting his thoughts down, then the book opens into something which you can relate to.
He explains how nothing is usually defined and most important things like success are very relative and vague for the most of us. We are made to see life through many viewpoints( which he calls as lenses). The basic underlying idea is that instead of following the worlds definition of life and success, the first step would be to define it on your own terms. Basically he details the whole idea of success and life using six important virtues which are to be custom defined as per oneself.
1. Purpose
2. Authenticity
3. Courage
4. Trust
5. Luck
6. Success
In most of these virtues he also guides us towards books from other authors we can refer, to have a deeper understanding of the one aspect of that virtue. I found the bits about how authenticity itself is relative to be interesting to read. All in all a good read and good subject to read all in all.
