William Green on what makes Joel Greenblatt a great investor

I try to explain the traits that he embodies that I think you need to be a great investor.  He has this kind of cold rationality, tremendous independence of mind, he's got guts, he's got these sturdy principles that he believes in through think and thin, he's super competitive, very disciplined, even-tempered, patient.
