It would be interesting to have you interview him IRL and ask him how he leads like this *on a consistent basis*. We all have bad days where we mess up as leaders yet he seems to remain outwardly positive and kind. Was he born this way or did he consciously make choices to become that kind of person?

Have you worked with anyone in the tech field who displayed this kind of leadership? DJ's passion for the "game" might be a major reason for his success. I wonder if that isn't the beginning step towards this kind of leadership? You have to be absolutely passionate about the thing foremost. If you're even slightly meh about the thing, it would be hard(er) to be a consistently kind person. Or be the Dalai Lama?
