Can the book The Greatest Salesman in the World really make you successful?

There are many books in this world that teach you how to succeed, such as Carnegie's road to success, Laura's school and so on, but none of them are successful after reading or following the book. Why?

Because success cannot be copied, everyone's family background, education level, emotional intelligence, IQ, environment and industry. Friends around me. You can even say that you have success genes in your own life. Will affect your final success. You are ambitious and want to succeed, which is a good thing, which shows that you are a person who knows how to make progress.

You just need to do what you want, not study by books. As the saying goes, "it is better to believe in books than to have no books." Books are dead and people are alive.
