It’s not uncommon for former law enforcement officers and intelligence agents to write self-help books where they share how the lessons they learned in their professional careers can apply to people in any walk of life.

What is rare is for one of these officers-turned-authors to publicly prove they know what they’re talking about and that their tips work, as Derrick Levasseur did by winning the reality show Big Brother.

Derrick is a former undercover detective, current private investigator, and the author of The Undercover Edge: Find Your Hidden Strengths, Learn to Adapt, and Build the Confidence to Win Life’s Game. Today on the show, Derrick shares how he became an undercover police officer, what he learned from that job, how he applied those lessons on Big Brother, and how you can use similar techniques to influence others, know when someone is lying, and bounce back from adversity.

When it comes to weight management and all-around good metabolic health, we most often think about what to eat. But my guest would say that it's also crucial to think about when to eat,

Emily Manoogian is a chronobiologist and clinical researcher at the Salk Institute for Biological Studies. Today on the show, Emily shares how to create an optimal schedule for a healthy metabolism by aligning your eating schedule with your circadian rhythm. She explains when to start eating after waking, when to stop eating before bed, the importance of sticking to a set schedule, and what happens to your metabolism when you don't follow these timing guidelines. We also talk about how to best distribute your calorie intake throughout the day and how to eat to mitigate the metabolic problems that come with being a shift worker.

In 18th century America, this book was second in popularity only to the Bible.

It was a favorite of many thinkers and leaders throughout history, including Emerson, Napoleon, Machiavelli, Nietzsche, and even President Truman.

Yet, you probably haven't read it.

It's Plutarch's Parallel Lives.

If you're not familiar with Plutarch's Lives, you're in for a treat, as today's episode offers a great intro. My guest, Alex Petkas, found that even though he's a former classicist and professor, Plutarch's Lives is still a tough read, which is why he started a podcast, The Cost of Glory, to make it more accessible to people. He does the same thing on today's episode, sharing the background on Plutarch's set of biographies and its major themes. Alex explains why Plutarch thought that biography was a powerful way to transmit morals and how the Homeric virtue he had in mind differed from that of just having good, upstanding character. Alex then gives us a taste of Plutarch as we discuss the lives of two obscure Greek and Roman figures. We end our conversation with how to get started studying Plutarch yourself.

This episode starts off a little differently than others — with a short quiz, something called the Brief Sensation-Seeking Scale, which will tell you whether you're what psychologists call a high sensation-seeker or a low sensation-seeker. Read the following eight statements, and then pick a number from 1 to 5 that corresponds to your level of agreement, where 1 is "Not at all like me," 2 is "Not like me," 3 is "Unsure or both like and not like me," 4 is "Like me," and 5 is "Very much like me."

1. I would like to explore strange places.
2. I would like to take off on a trip with no pre-planned routes or timetables.
3. I get restless when I spend too much time alone.
4. I prefer friends who are excitingly unpredictable.
5. I like wild parties.
6. I would love to have new and exciting experiences, even if they are illegal.
7. I would like to try bungee jumping.
8. I would like to do frightening things.

Now add up all the numbers together. If you scored between 8 and 16, you are a low sensation-seeker. If you scored between 16 and 28, you're about average for sensation-seeking. If you scored over 28, you're a high sensation-seeker.

Today on the show, I unpack what these categories of personality mean with Dr. Kenneth Carter, a clinical psychologist, a professor, and the author of Buzz!: Inside the Minds of Thrill-Seekers, Daredevils, and Adrenaline Junkies. Ken explains how sensation-seeking exists on a spectrum between chill seekers, who like safety and calm routine, and thrill seekers, who enjoy chaos, risk, and novelty. He shares how there are actually four components to high sensation-seeking, and which two tend to get people in trouble. And we talk about whether being high or low sensation-seeking is a matter of nature or nurture, how high sensation-seekers fare in romantic relationships and what they should consider in choosing a career, and what the world's chill seekers can learn from its thrill seekers.

“Nothing takes the taste out of peanut butter quite like unrequited love,” Charlie Brown once said. Indeed, being spurned by one's crush, or, for that matter, by a friend or potential employer, not only ruins the taste of one's favorite sandwich spread, but causes great psychological distress and even physical pain.

Here to walk us through one of life's worst feelings is Mark Leary, a professor of psychology and neuroscience at Duke University, and the editor of Interpersonal Rejection. Today on the show, Mark unpacks the experience of social rejection, including why we're so sensitive to it and the emotions and behaviors it causes, which can be positive and prosocial or maladaptive and even violent. We discuss the role that is played by the sociometer, a concept Mark originated, in monitoring our social acceptance and rejection and what influences its sensitivity to fluctuations in your relational value. And Mark offers advice on how to remove some of the sting of rejection and civilly reject others.

In creating the Jack Reacher character, Lee Child launched a series of books that now boast 100 million copies in print and have been turned into movies and a popular Amazon streaming series.

Today on the show, I talk to Lee about what makes Reacher so compelling and much more. We first discuss how Lee didn't get started with writing until he was almost forty, and what prompted him to change careers. We then unpack the Reacher character, discussing the ancient, archetypal roots of this vigilante, drifter detective, what he has in common with the knight errant, and the enduring appeal of the lone wolf. We also talk about Lee's writing process, why midlife is the best time to write, and why, after writing more than two dozen Reacher novels, he's chosen to hand off the series to his brother and fellow writer, Andrew.

Money can't buy happiness. It sounds good as a bumper sticker platitude.

But the truth is, money can buy happiness. At least sometimes. In certain circumstances. If we view it and use it in the right ways.

Here to unpack the conditions under which money can buy happiness and facilitate our flourishing is Dr. Daniel Crosby, a psychologist and behavioral finance expert and the author of The Soul of Wealth: 50 Reflections on Money and Meaning. Today on the show, Daniel shares the minimum income level at which money buys happiness, at least in the sense of avoiding pain. We talk about how to purchase material things in a way that increases happiness, while avoiding materialism, and the value of using your money to buy health and freedom. And we discuss the importance of finding an overarching why that guides the way you allocate your money and doing a values audit to see if your purpose and spending habits are aligned.
