Here's The Best Advice The World's Most Successful People Have Ever Received

"To be interesting, you have to be interested."

If you could ask anyone for life advice, who would it be?

Given the opportunity, chances are a super successful actor, producer, CEO, news anchor, tech mogul, or business person would be on your list. 

In October, Vanity Fair hosted the 2015 New Establishment Summit, an event that gathered successful "titans of technology, politics, business, and media" together to have "inspiring conversations around the ideas and innovations shaping the future," according to the magazine's website.

Event speakers included Maria Shriver, Lena Dunham, Elon Musk, Mark Zuckerberg, Elizabeth Holmes, Rashida Jones, Lee Daniels, Katic Couric, and Andrew Ross Sorkin, among many others.

And luckily for us, many of these speakers shared the best advice they've ever gotten (as well as their own words of wisdom) in a video uploaded to Vanity Fair's YouTube channel.
