I have met many entrepreneurs who have the passion and even the work ethic to succeed - but who are so obsessed with an idea that they don't see its obvious flaws. Think about that. If you can't even acknowledge your failures, how can you cut the rope and move on?
I'm particularly struck by the neo-socialist concern for the well-being of plants, animals, lakes and rivers, rain forests and deserts - particularly when the concern for the environment appears far more intense than the concern for the human family.
