I recently found the following question and answer session between Warren Buffet and a group of MBA students on Kempton’s blog. Obviously, as a value investor, I pay close attention to what the “Oracle of Omaha” has to say. What impressed me most about this video, though, was Buffet’s personal philosophy. He’s the least materialistic billionaire the world has ever seen, and his values show through clearly in this speech. “Do what you love. Have integrity.” That’s his message.
