Speaker 1 (0:00) There were 96 United States senators the year Harry Truman became president. Historians believe that 95 of them could have done his job just as well as he did. Somewhere in your own life right now, there's a version of you just as replaceable, showing up to do something almost anyone in your seat would have done anyway. And there's another version of you in a different room that nobody on earth could ever replace. Today, we're going to figure out which one you were this week. It's your friend John, and welcome to Passion Struck. I'm so glad you're here. Whether you're a longtime listener or someone who just discovered the show, thank you for pressing play today. Maybe you've built the life you were supposed to want, but you've quietly wondered why it still doesn't feel like enough. Speaker 1 (0:54) If that's you, you're in the right place. Every week, I sit down with the world's top scientists, researchers, and thinkers to uncover what it actually takes to build an intentional life that matters. Thanks for joining me. Let's get into it. Speaker 1 (1:14) Welcome back to episode 816 of Passion Struck. We're closing out week one of a brand new series, The Adaptive Human, How We Thrive in a Changing World. Before we get back to those 95 replaceable senators, I want to tell you where I actually was for the last two weeks. Because it's the reason I did two interviews the past two weeks. And it's the reason that question isn't abstract to me right now. I spent two weeks up in Blue Ridge, Georgia, secluded in a cabin, boating on Lake Notley, hiking to waterfalls I'd never seen before. No calendars, no notifications, no version of my normal life. Somewhere around day four, I noticed something that bothered me a little, if I'm honest. I felt like a better version of myself. Speaker 1 (2:11) than I'd felt like in months. Clearer, slower, more patient. And none of that was because I tried harder to be that person. It was because I wasn't in the same environment anymore. I got home Saturday night. And this week, the same week we launched this series, the same week you heard from both of this week's guests, has been my live test of whether any of that actually stuck. I think what actually happened up there is that I got situated. That word isn't an accident. It's the title of a new book that landed this very week from a guest you heard right here on Tuesday, Angela Duckworth. Her whole argument after a career spent studying grit is that grit was never the whole story. You can have all the willpower in the world, Speaker 1 (3:07) and still lose to a bad situation. Sometimes the answer isn't trying harder. It's standing somewhere else, which is a nice, tidy truth when you're talking about a lake in Georgia. It gets a lot less tidy when you scale it up, which is exactly where Thursday's conversation took us. Because the same week I was reading Advanced Pages of Angela's book, I was also sitting down with Jared Diamond, who asks almost the identical question, but not about a person on vacation, about the people who shape history. So here's what today is actually about. Two books from two completely different fields landing in the same week, both circling one uncomfortable question. When does the person actually matter? And when? Speaker 1 (4:02) Is it really just the room? You already heard both of them make their individual cases this week. Today, I want to put those two conversations next to each other and next to my own very ordinary week and see what falls out. And by the end of this episode, I'm going to give you one tool for telling the difference in your own life. I call it the fit check. Two questions. It takes about 10 seconds. and I already ran in on myself this week, so I'll tell you exactly what it told me. Here's what's ahead. What Angela Duckworth told me about the moment she realized grit was never the whole story, and the Fortune 500 story that proved it to her. A term one Stanford researcher used in her book that sounds almost exactly like something I've spent two years building a book around. The test Jared Diamond uses to figure out if a leader actually mattered. Speaker 1 (4:58) and what happened when I turned that same test on myself this week, and the honest answer to whether that mountain version of me made it home. Let's get into it. Thank you for choosing PassionStruck and choosing me to be your host and guide on your journey to creating an intentional life that matters. Now, let that journey begin. Speaker 1 (5:25) Let's start with the obvious question about Blue Ridge, Georgia. Was I actually a better person up there, or did I just
