You might know Warren Buffett as the No. 2 richest man in the world according to Forbes, but he recently met his Forbes match when he sat down with Jay-Z, who topped the publication’s Hip-Hop Cash Kings list this year.

The two chopped it up at the first Forbes 400 summit, which took place in Buffett’s native Omaha, Neb. The entrepreneurs chatted for over an hour about their perspectives on wealth, their definitions of success, and the responsibilities that come with having money, power, and respect.

“Develop the habits of success. Look around you at the people you admire, and list what makes you admire them compared to someone else,” advised Buffett to Hov. “What am I going to say to this guy?” joked Jay when asked to offer some advice to the billionaire.
