In Money (actually the Money Investor's Guide 2010′s Professional User's Guide, which comes free to FPA members with added information), there is information from The Elements of Investing by Burton C. Malkiel and Charles D. Ellis (Wiley, 2010). Both men are exceptional authors and investors (Malkiel, for example, wrote A Random Walk Down Wall Street and Ellis is considered one of the best investment writers living). In an article excerpted from their book, "Dodge the 6 Biggest Investing Mistakes," Messrs. Malkiel and Ellis say this:
"We're both in our seventies. So is Warren Buffett. The main difference between his spectacular results at Berkshire Hathaway and our good results is not the economy and not the market, but the man from Omaha. He is simply a better investor than just about any other in the world. Brilliant, consistently rational, and blessed with a superb mind for business, he has managed to avoid the mistakes that have crushed so many portfolios."
