Rich Dad Poor Dad is a story based on the author and how his two fathers, the first his poor biological father and the other his rich dad who is his childhood best friend Mike's father, teach him the ways of achieving success in very different manners. The author is seen comparing both the fathers during the progression of the book. He takes in account their thoughts, values and business practices. The author differentiates amongst his poor and struggling, yet highly educated father, from his richer dad in terms of professional understanding and strength building. The poor dad is seen as a person who is in a continuous run in the rat race, but is never able to achieve his dreams for wealth as he lacks business knowledge. His rich dad forms the richer part of the public. The theme of the book is reduced down to two main thoughts - the will to succeed and being a fearless businessperson. These two ideas are highlighted, as the book presents many examples for each. The book focuses on how an individual should have good knowledge of money and the rigid faith that an individual's upbringing obstructs their economic goals. The book has sold more than 26 million copies and is also a New York Times Bestseller. The book has been endorsed by Oprah Winfrey and Will Smith.
