It's been seven months since Mark Zuckerberg announced his personal challenge for 2017: Travel to the 30 states in America he's never visited and speak with residents--and he's making quick progress. But if the Facebook CEO comes knocking on your door, there are some things you should know.

Zuckerberg's visits are usually announced last minute, but if you do find out beforehand, keep the information secret. Despite the fact that Zuckerberg made billions from a company that encourages people to share the details of their lives, he doesn't want the specifics of the meetings leaking, according to The Wall Street Journal. When one person mentioned that Zuckerberg would be at the Kusanya Café in Chicago, employees at the coffee shop had to set up extra folding chairs for the 100 people who came to see him, the Journal reported.

In January, Zuckerberg announced his New Year's Resolution, an annual tradition for the 33-year-old billionaire. In 2009, he vowed to wear a tie every day, and in 2011, he promised he would only eat meat from animals that he personally killed. "After a tumultuous last year, my hope for this challenge is to get out and talk to more people about how they're living, working, and thinking about the future," he wrote on his Facebook page.

So far, the social-media titan has been to 20 states on his tour, with a focus on the Southern and Midwestern regions of the U.S. He's walked the streets of New Orleans for Mardi Gras, dined on local salmon with "Native Alaskans," and worked on a farm in Wisconsin. "I think the commonality is that in every community, there are certain entrepreneurs or leaders who really organize and get people motivated to go do stuff," Zuckerberg told Recode.

Even though Zuckerberg wants you to keep mum about the meetings, there's one thing you are allowed to tell the press. "If there are any news reporters that call you, just make sure you tell them I'm not running for president," Zuckerberg told the Moore family in Ohio, according to Journal.
