@investments: Warren Buffett is one of the most successful investors in history, and he attributes all of his success to one book: The Intelligent Investor. Buffett first read the book at age 19, and it had a profound impact on the way he thought about investing. Even today, at 92 years of age, Buffett still uses the same principles and thought processes that he learned from the book. It's amazing how one book can have such a lasting impact on an individual. Warren Buffett is living proof that the right book can change your life. Correction: his birthday was yesterday, August 30th.
