"Warren and I get nervous with vast amounts of leverage unless we're 100% confident that risk-taking won't creep into the culture."

"It reminds me of a guy running a company who fired his top producer. The guy asked him, 'Why are you firing me? I'm your top producer.' To which he responded, 'You make me nervous. I'm a rich old man. Why should I be nervous?" (Charlie Munger on Wesco's 2002 Annual Meeting)
