Nvidia CEO Jensen Huang's indefatigable work ethic has helped turn the chip giant into one of the most valuable companies in the world.

So it's perhaps no surprise that Huang's client and fellow billionaire, Elon Musk, is a fan of his management style.

"Absolutely the right attitude," Musk said in an X post on Sunday. "During the toilet paper shortages of Covid, I was making sure that our factories and offices had toilet paper."

Musk was responding to a clip of an interview Huang gave in March to Stanford's Graduate School of Business, where he talked about his experience working at the breakfast chain Denny's.
