Rather, the takeaway is this: For the cost of a cup of a coffee--or maybe a meal--you should check in with your mentors or reach out to someone with whom you can potentially cultivate a mentor relationship. Often, you don't have to cross the ocean to gain insight and perspective. You just have to network with people you really respect. And listen to what they say.

And if you think Zuckerberg's relationship-building chops are limited to celebrity mentors, think again. Two years ago, after Facebook's $19 billion acquisition of WhatsApp made huge news, the New York Times reported that Zuckerberg and WhatsApp co-founder and CEO Jan Koum negotiated the deal over a plate of chocolate-covered strawberries at Zuckerberg's house.

Think about this. When was the last time you visited someone's house and ate chocolate-covered strawberries? Does that seem like something likely to happen during a rigorous due diligence process? Or does it require a certain level of familiarity and friendship?

As it turns out, Zuckerberg and Koum are friends. In recent years, noted the Times, they'd shared dinners and gone on hikes together. And while Koum had 19 billion reasons to choose Facebook's offer, there was evidence that this deal was about more than money--for both the buyer and the seller. It was about the alignment of long-term visions. Indeed, Facebook assured Koum that WhatsApp would remain ad free--and gave him a seat on Facebook's board.
