1. Caitlyn Jenner’s ‘Caitlyn’ necklace: “An ESPYs producer gave it to me right before the show, which was my first public appearance as my authentic self,” says the reality star and trans-rights activist. “This little necklace—and the name on it—represents the struggle I’ve been through all my life.” Cassidy Paul for TIME
2. Christiana Figueres’ P.G. TIPS tea: “I organize my day around it, even when I’m traveling,” says the Costa Rican diplomat. “It’s very, very strong, and it bumps my energy up.” Cassidy Paul for TIME
3. Eli Broad’s Paperweight: “My wife gave it to me early in our marriage, and it has been on my desk for more than 50 years,” says the billionaire philanthropist. “I like the quote, from George Bernard Shaw, because I believe it. I do not follow conventional wisdom.”Cassidy Paul for TIME
4. John Kerry’s Favorite Desk: “When people come to the State Department, I love showing them the desk on which the Treaty of Paris—which ended the Revolutionary War—was signed,” says the Secretary of State. “It underscores that peace is possible: you can end the war, you can sign an agreement.”U.S. Department of State
5. Katie Ledecky’s Power Snack: “I never had much chocolate milk as a kid,” says the Olympic swimmer. “But now I always have it right after practice, with yogurt, so I can get the right amount of protein and carbs to keep me going."Cassidy Paul for TIME
6. Nikki Haley’s ‘Believe’ Stone: “I look at it every morning,” says the South Carolina governor. “It reminds me to believe in myself and to believe in the goodness of people.
7. Priyanka Chopra’s Charm Necklace: My dad used to be my best friend and my lucky charm,” says the star of ABC’s Quantico. “So when he got cancer, my family and I tried to appeal to every god around. We collected healing charms from all over the world—including Jerusalem and a mosque in India—and we put them on this necklace. Now that he’s gone, I carry it with me wherever I go. It’s sort of like having my dad with me again.”
8. Ryan Coogler’s Warriors Hat: “Where I’m from in the Bay Area, we’ve got two teams for most sports—the A’s and the Giants, the Raiders and the 49ers,” says the Creed director. “What’s cool about the Warriors is they’re our only basketball team, so everyone can agree on them. As a kid, some of my finest memories were at those games. So when we shot Creed in Philadelphia, I almost always wore a Warriors hat. It made me feel like I had a little piece of home with me.” Fanatics
9. Ta-Nehisi Coates’ Rihanna album and earbuds: “Anti is such a left turn from what Rihanna usually does, and I admire that courage,” says the best-selling author, “because when people are cheering for you, there’s a deep temptation to avoid taking chances. When I listen to it, I’m really inspired, in my own work, not to end up writing the same thing over and over.”Cassidy Paul for TIME
