There are bosses, and then there are superbosses.
What is a superboss? It’s not that they are giants themselves (which they are), but that they hire other giants as well.
Virgin founder and CEO, Richard Branson once said; he wanted people who’d be millionaires on their own steam working for him, so in order to get them on board he needed to make them millionaires.
It’s that wonderful balance of having an ego big enough to handle these top-tier people, yet having enough humility to hire people smarter/better than you. It’s harder than it looks.
