Are you an Upholder, a Questioner, an Obliger, or a Rebel? From the author of Better Than Before and The Happiness Project comes a groundbreaking analysis of personality type that will immediately improve every area of your life.

Gretchen Rubin realized that by asking the seemingly dry question "How do I respond to expectations?" we gain explosive self-knowledge. She discovered that based on their answer, people fit into Four Tendencies:

• Upholders meet outer and inner expectations readily.
• Questioners meet inner expectations, but meet outer expectations only if they make sense.
• Obligers (the largest Tendency) meet outer expectations, but struggle to meet inner expectations.
• Rebels resist all expectations, outer and inner alike.

Our Tendency shapes every aspect of our behavior, so using this framework allows us to make better decisions, meet deadlines, suffer less stress, and engage more effectively. It's far easier to succeed when you know what works for you. With sharp insight, compelling research, and hilarious examples, The Four Tendencies will help you get happier, healthier, more productive, and more creative.

Leaders Eat Last: Why Some Teams Pull Together and Others Don't explores the concept of leadership and the critical role it plays in the success of an organization. Simon Sinek delves into the idea that exceptional leaders create an environment of trust and cooperation, often at the expense of their own comfort and survival, for the benefit of those in their care.

Based on real-world experiences and true stories from various domains, including the military and business sectors, Sinek introduces the Circle of Safety—a principle that fosters stable, adaptive, and confident teams where individuals feel a sense of belonging. This book not only provides insights into leadership but also uncovers the biological underpinnings of why some teams excel while others struggle.

With an expanded focus on leading millennials, Sinek's narrative is further enriched by his observations on how the greatest leaders in history have always prioritized the well-being of their people, creating a culture where everyone works together to achieve remarkable outcomes.

A few years ago, Chimamanda Ngozi Adichie received a letter from a dear friend from childhood, asking her how to raise her baby girl as a feminist. Dear Ijeawele is Adichie's letter of response.

Here are fifteen invaluable suggestions -compelling, direct, wryly funny, and perceptive- for how to empower a daughter to become a strong, independent woman. From encouraging her to choose a helicopter, and not only a doll, as a toy if she so desires; having open conversations with her about clothes, makeup, and sexuality; debunking the myth that women are somehow biologically arranged to be in the kitchen making dinner, and that men can "allow" women to have full careers, Dear Ijeawele goes right to the heart of sexual politics in the twenty-first century. It will start a new and urgently needed conversation about what it really means to be a woman today.

Many people dream of escaping modern life, but most will never act on it. The Stranger in the Woods: The Extraordinary Story of the Last True Hermit tells the remarkable true story of Christopher Knight, a man who lived alone in the woods of Maine for 27 years, not out of anger at the world, but simply because he preferred to live on his own.

In 1986, a shy and intelligent twenty-year-old named Christopher Knight left his home in Massachusetts, drove to Maine, and disappeared into the forest. He would not have a conversation with another human being until nearly three decades later, when he was arrested for stealing food. Living in a tent even through brutal winters, he had survived by his wits and courage, developing ingenious ways to store edibles and water, and to avoid freezing to death. He broke into nearby cottages for food, clothing, reading material, and other provisions, taking only what he needed but terrifying a community never able to solve the mysterious burglaries.

Based on extensive interviews with Knight himself, author Michael Finkel provides a vividly detailed account of Knight's secluded life—why did he leave? what did he learn?—as well as the challenges he has faced since returning to the world. It is a gripping story of survival that asks fundamental questions about solitude, community, and what makes a good life, and a deeply moving portrait of a man who was determined to live his own way, and succeeded.

A young woman follows winter across five continents on a physical and spiritual journey that tests her body and soul, in this transformative memoir, full of heart and courage, that speaks to the adventurousness in all of us.

Steph Jagger had always been a force of nature. Dissatisfied with the passive, limited roles she saw for women growing up, she emulated the men in her life—chasing success, climbing the corporate ladder, ticking the boxes, playing by the rules of a masculine ideal. She was accomplished. She was living The Dream. But it wasn't her dream.

Then the universe caught her attention with a sign: Raise Restraining Device. Steph had seen this ski lift sign on countless occasions in the past, but the familiar words suddenly became a personal call to shake off the life she had built in a search for something different, something more.

Steph soon decided to walk away from the success and security she had worked long and hard to obtain. She quit her job, took a second mortgage on her house, sold everything except her ski equipment and her laptop, and bought a bundle of plane tickets. For the next year, she followed winter across North and South America, Asia, Europe, and New Zealand—and up and down the mountains of nine countries—on a mission to ski four million vertical feet in a year.

What hiking was for Cheryl Strayed, skiing became for Steph: a crucible in which to crack open her life and get to the very center of herself. But she would have to break herself down—first physically, then emotionally—before she could start to rebuild. And it was through this journey that she came to understand how to be a woman, how to love, and how to live authentically.

Electrifying, heartfelt, and full of humor, Unbound is Steph's story—an odyssey of courage and self-discovery that, like Wild and Eat, Pray, Love, will inspire readers to remove their own restraining devices and pursue the life they are meant to lead.
