Look for the moat

We don't do due diligence or go out kicking tires. It doesn't matter. What matters is understanding the competitive dynamics of a business. We can't be taken by a guy with a sales pitch... What really counts is the presence of a competitive advantage. You want a business with a big castle and a moat around it, and you want that moat to widen over time. Coke and Kodak both had marvelous moats 20 or 25 years ago. Kodak's has narrowed, while Coke has been building its moat. We want an economic castle.
