The book is well suited for people who have little knowledge or experience with investment. The author shares the principles and investing method that earned him the financial freedom he now enjoys. What I found particularly useful are the chapters explaining his stock investing system, which is very easy to understand, set up, implement, and track over time. Moreover, his system strikes a good balance between risk and return, thus complementing well one's plan to achieve long-term financial goals. It's probably not 100% perfect for everyone, but his system is a good starting point from which one can further customize.
