When I tried reading this book in college, I really couldn't relate. After a few years in the "jungle" (in my case NYC, financial difficulty, relationship problems), I felt that this book, unlike others which focus almost exclusively on positive, optimistic, and goal-seeking attitudes as answers to life, was on the money.
Robert writes about value-for-value relationships (akin to the law of kharma/psychological reciprocity), and how this concept determines the outcome and rewards of relationships, whether love, friendship or employer.
I have studied psychology, and have read more than twenty self-help books, and though this might be a little surprising (in the sense that people might find it cynical to an extent), I think there's so much truth to it. And because of the title, I found myself telling people "it's a good message - it's not about stepping on others." In fact, when one looks out for him/herself, that's when he can give or provide to someone else if he/she wants, and what he or she can give. So, it's also a message of independence. I've seen it happen where people help and give, sometimes giving what they cannot, and they end up frustrated, and things are worse than where they begin.
Though the book might seem a bit cynical, I think it is on the money, and Robert was an author who could come forth and talk about reality (though I think we all need to escape it once in a while, or not focus on the negativity).
I can related to a lot of what is in this book, though sometimes I do not want to believe in all of it - but it's reality. And I've found myself losing touch with it at the wrong times, and this book gives me a great message that will prepare me for future situations.
Good job Robert.
