Starting from scratch, it took the world's greatest investor, Warren Buffett, nearly five decades to make his first $100m. This book explains the reasoning behind each investing milestone on that journey, tracks the deals he made and shows how they added to his wealth.Without much of an idea about investing in shares at the beginning, Buffett had to develop his investment philosophy, and learn through success and failure how to select companies worth backing. It was not all plain sailing, with many mistakes along the way; and there were long periods of frustration with the market. The fact that Buffett made errors is quite reassuring for other investors. The key is to learn from them, and to accept with evenness of temper the many bumps in the road.
