How should you approach your investments? How should you think about them? Those are the types of questions Chris Mayer tackles in his newest book, How Do You Know: A Guide to Clear Thinking About Wall Street, Investing, and Life. Through a series of provocative-and often amusing-examples, Chris puts those perennial investing questions into a much larger context... How do you know anything at all? His answer, which is sure to make many readers uncomfortable is... you don't. How Do You Know? is not another book on investing. It is full of ideas about investing, including one that hasn't been part of the public investing discussion in nearly 60 years. But Chris' goal is not just to give you ideas, but to provide practical guidelines for uncluttering your thinking-that is, for getting unhelpful ideas and misleading information out of the way.
