Having read the post and comments, the entire argument seems to be "Some don't want to work for a narcissistic, work-obsessed outspoken boss" and "narcissistic, work-obsessed outspoken people make it".

You know the single thing that every single successful entrepreneur, in any field, has in common? They're work-obsessed. They bust their balls. I'd rather work for someone like JC than a work-shy narcissist.
