My books review: Money for the rest of us

Overview: The "Money for the rest of us" book is a list of 10 questions serve as a guideline to invest. It is light book with not many pages and can be read during commute time. The book does not require audiences to have any special knowledge. My impression: The author, Mr. David, is very friendly and patient to answer my questions. The 10 questions are greatly explained by the author, and I think they provide a good starting point. However, I think anyone who wants to invest should build their own checklist and a general guideline for different situations. When a general guideline is in place, the decisions need to respect the guideline in order to make consistent decision. Consistency , in my opinion, is the most important in the long run as it provide information for constant feedback and improvements. Overall, I think this is a good book that helps improving my decision making process. - ninjahoahong
