This Week in Thought Leaders: Sleeping Your Way to the Top, Calling Out Jack Welch's Theories, More

This week, we assembled the biggest names in business and gave them a challenge: Share something interesting with 175 million professionals.

Arianna Huffington delved into the science of sleep. Mohamed El-Erian explained why he’s still concerned about Europe. And Andrew Chen reflected on his friend, Noah Kagan, who lost out on a $100 million Facebook fortune.

The insights, part of LinkedIn's new thought leader program, spanned across industries and veered into politics, philanthropy and even food. Barack Obama and Mitt Romney outlined how they’d create jobs, while Panera Bread’s founder and co-CEO, Ron Shaich, sounded off on why he’s counting the days until Nov. 7.

The most popular post of the week, however, came from Richard Branson, the billionaire entrepreneur who attracted more than 100,000 followers in just 72 hours by describing the five secrets to starting a successful business. (No. 1: Listen more.)

Sallie Krawcheck: Why the Glass-Steagall Debate Doesn't Matter So many ex-bankers have come forward with ideas on how to simplify the financial system that “it’s a bit like watching an alumni basketball game.” But, like a basketball game, this score doesn’t particularly matter, Krawcheck says.

Eric Ries: How a Behemoth Like Nordstrom Learned to Act Like a Startup Nordstrom, with its $9 billion in annual revenue, isn’t exactly a nimble up-and-comer. But, it’s starting to act like one. Ries goes inside the company to see how one-week iterations, Toyota-inspired production techniques and lots of testing are reshaping how the retailer does business.

Peter Guber: Why You Should Aim for the ‘Red Zone’ in Business When Guber recently bought part of the LA Dodgers with a group of business partners, he was “flying in the red zone.” Business leaders, he says, need to do the same.

Steve Rubel: Managing a Transition: Larry Kramer, USA Today USA Today changed the news business 30 years ago with its graphics-heavy pages and short, easy-to-read stories. But can it reinvent itself for the digital era? Rubel sits down with USA Today’s new publisher, Larry Kramer.
