The best business returns are usually achieved by companies that are doing something that it's hard or impossible for you to do to them. Every year they get harder and harder to compete with. They have an ever-widening moat around their castle, and the key is not 'how big is the castle today?' but 'what is the trajectory of the moat?'

— Warren Buffett, Berkshire Hathaway Annual Meeting (1995)
