Disappointing investments are often written off as bad luck, but the author of this investment guide holds the keys to making your own luck. Written in a direct and affable style by an amateur psychologist and student of human nature, these adventures of an "outsider" recount a Wall Street success story and offer a valuable study of crowd reaction to market fluctuations. He outlines the benefits of "contrary thinking" and shows how this style of thinking outside the box can lead to success in investing as well as other endeavors. The author identifies the four greatest enemies to stock market prosperity, and shows how to recognize and avoid them in instructive chapters such as "Vanity," "Greed," and "The Will to Believe."
