Mixing business and pleasure might be frowned upon, but that doesn’t mean you shouldn’t have business cards on you at all times. You never know when you’re going to run into a potential business partner – or a free lunch fishbowl – so best to be prepared. Unless you want to advertise the fact you’re only as serious as a crumpled business card, you need a card holder. Something just the right amount of flashy and memorable. Like a silver card case engraved with “I’m CEO…bitch” Based on his success, taking a page out of Zuckerberg’s book isn’t a bad business decision.
