The first chapter was interesting. From everything I read, I agreed with 80%, the other 20% that I don't agree with are for things like for example: 1. The definition of success. Success is relative, and the key to true success is a good relationship with God and then part of what the book mentioned. If you consider yourself successful for what you have, when you lose it then you will also stop being successful 2. Believe in yourself. It's extremely important, but you also have to be realistic. If a cat thinks it's a lion and fights with another lion, we all know what will happen. So, although you have to believe in yourself, recognize your limits and try to overcome them. 3. To be happy you don't need to be successful. If you only focus on getting the things that people consider successful to feel happy, you will never be happy. To be happy, you have to enjoy the things that lead you to success, (enjoy the road and value every small step you achieve)
