by Carol S. Dweck

Mindset is one of those rare books that can help you make positive changes in your life and at the same time see the world in a new way.A leading expert in motivation and personality psychology, Carol Dweck has discovered in more than twenty years of research that our mindset is not a minor personality quirk: it creates our whole mental world. It explains how we become optimistic or pessimistic. It shapes our goals, our attitude toward work and relationships, and how we raise our kids, ultimately predicting whether or not we will fulfill our potential. Dweck has found that everyone has one of two basic mindsets.If you have the fixed mindset, you believe that your talents and abilities are set in stone--either you have them or you don't. You must prove yourself over and over, trying to look smart and talented at all costs. This is the path of stagnation. If you have a growth mindset, however, you know that talents can be developed and that great abilities are built over time. This is the path of opportunity--and success.Dweck demonstrates that mindset unfolds in childhood and adulthood and drives every aspect of our lives, from work to sports, from relationships to parenting. She reveals how creative geniuses in all fields--music, literature, science, sports, business--apply the growth mindset to achieve results. Perhaps even more important, she shows us how we can change our mindset at any stage of life to achieve true success and fulfillment. She looks across a broad range of applications and helps parents, teachers, coaches, and executives see how they can promote the growth mindset. Highly engaging and very practical, Mindset breaks new ground as it leads you to change how you feel about yourself and your future."This book is an essential read for parents, teachers, coaches, and others who are instrumental in determining a child's mind-set, and in turn, his or her future success, as well as for those who would like to increase their own feelings of success and

by Clarissa Pinkola Estés

Within every woman there is a wild and natural creature, a powerful force, filled with good instincts, passionate creativity, and ageless knowing. Her name is Wild Woman, but she is an endangered species. Though the gifts of wildish nature come to us at birth, society's attempt to "civilize" us into rigid roles has plundered this treasure, and muffled the deep, life-giving messages of our own souls. Without Wild Woman, we become over-domesticated, fearful, uncreative, trapped. Clarissa Pinkola Estes, Ph.D., Jungian analyst and cantadora storyteller, shows how woman's vitality can be restored through what she calls "psychic archeological digs" into the ruins of the female unconscious. In Women Who Run with the Wolves, Dr. Estes uses multicultural myths, fairy tales, folk tales, and stories chosen from over twenty years of research that help women reconnect with the healthy, instinctual, visionary attributes of the Wild Woman archetype. Dr. Estes collects the bones of many stories, looking for the archetypal motifs that set a woman's inner life into motion. In Women Who Run with the Wolves, Dr. Estes has created a lexicon for describing the female psyche. Fertile and life-giving, it s a psychology of women in the truest sense, a knowing of the soul.

by John E. Douglas, Mark Olshaker

Discover the classic, behind-the-scenes chronicle of John E. Douglas’ twenty-five-year career in the FBI Investigative Support Unit, where he used psychological profiling to delve into the minds of the country’s most notorious serial killers and criminals—the basis for the upcoming Netflix original series. In chilling detail, the legendary Mindhunter takes us behind the scenes of some of his most gruesome, fascinating, and challenging cases—and into the darkest recesses of our worst nightmares. During his twenty-five year career with the Investigative Support Unit, Special Agent John Douglas became a legendary figure in law enforcement, pursuing some of the most notorious and sadistic serial killers of our time: the man who hunted prostitutes for sport in the woods of Alaska, the Atlanta child murderer, and Seattle's Green River killer, the case that nearly cost Douglas his life. As the model for Jack Crawford in The Silence of the Lambs, Douglas has confronted, interviewed, and studied scores of serial killers and assassins, including Charles Manson, Ted Bundy, and Ed Gein, who dressed himself in his victims' peeled skin. Using his uncanny ability to become both predator and prey, Douglas examines each crime scene, reliving both the killer's and the victim's actions in his mind, creating their profiles, describing their habits, and predicting their next moves.

by Adrian Raine

In this book a pioneering neurocriminologist introduces the latest biological research into the causes of, and potential cures for, criminal behavior. As a leading criminologist who specializes in the neuroscience behind criminal behavior, the author introduces a wide range of new scientific research into the origins and nature of violence and criminal behavior. He explains how impairments to areas of the brain that control our ability to experience fear, make decisions, and feel empathy can make us more likely to engage in criminal behavior. He applies this new understanding of the criminal mind to some of the most well-known criminals in history. And he clearly delineates the pressing considerations this research demands: What are the causes of violence? Can it be treated? And might it one day be stopped? Are some criminals born, not made? What causes violence and how can we treat it? This book introduces new ways of looking at these age-old questions. Drawing on the latest scientific research, the author explains what it reveals about the brains of murderers, psychopaths and serial killers. While once it was thought upbringing explained all, and subsequently explanations shifted to genetics, he goes to great pains to explain that anti-social behaviour is complex, and based on the interaction between genetics and the biological and social environment in which a person is raised. But the latest statistical evidence between certain types of biological and early behavioural warning signs is also very strong. Through a series of case studies of famous criminals, he shows how their criminal behaviour might be explained on the basis of these new scientific discoveries. But the conclusions point to a host of philosophical and moral issues. What are the implications for our criminal justice system? Should we condemn and punish individuals who have little or no control over their behaviour? Should we act preemptively with people who exhibit strong biological predisposition

by Mihaly Csikszentmihalyi

Psychologist Mihaly Csikszentmihalyi's famous investigations of "optimal experience" have revealed that what makes an experience genuinely satisfying is a state called *flow*. During flow, people typically experience deep enjoyment, creativity, and a total involvement with life. In this new edition of his groundbreaking classic work, Csikszentmihalyi demonstrates the ways this positive state can be controlled, not just left to chance. *Flow: The Psychology of Optimal Experience* teaches how, by ordering the information that enters our consciousness, we can discover true happiness and greatly improve the quality of our lives.

<b>#1 <i>NEW YORK TIMES </i>BESTSELLER • Brené Brown has taught us what it means to dare greatly, rise strong, and brave the wilderness. Now, based on new research conducted with leaders, change makers, and culture shifters, she’s showing us how to put those ideas into practice so we can step up and lead.<br><br>Don’t miss the five-part Max docuseries <i>Brené Brown: Atlas of the Heart</i>!<br><br>ONE OF <i>BLOOMBERG</i>’S BEST BOOKS OF THE YEAR</b><i><br></i><br>Leadership is not about titles, status, and wielding power. A leader is anyone who takes responsibility for recognizing the potential in people and ideas, and has the courage to develop that potential.<br><br>When we dare to lead, we don’t pretend to have the right answers; we stay curious and ask the right questions. We don’t see power as finite and hoard it; we know that power becomes infinite when we share it with others. We don’t avoid difficult conversations and situations; we lean into vulnerability when it’s necessary to do good work.<br><br>But daring leadership in a culture defined by scarcity, fear, and uncertainty requires skill-building around traits that are deeply and uniquely human. The irony is that we’re choosing not to invest in developing the hearts and minds of leaders at the exact same time as we’re scrambling to figure out what we have to offer that machines and AI can’t do better and faster. What can <i>we</i> do better? Empathy, connection, and courage, to start.<br><br>Four-time #1 <i>New York Times</i> bestselling author Brené Brown has spent the past two decades studying the emotions and experiences that give meaning to our lives, and the past seven years working with transformative leaders and teams spanning the globe. She found that leaders in organizations ranging from small entrepreneurial startups and family-owned businesses to nonprofits, civic organizations, and Fortune 50 companies all ask the same question:<br><br><b>How do you cultivate braver, more daring leaders, and how do you embed the value of courage in your culture?</b><br><br>In <i>Dare to Lead</i>, Brown uses research, stories, and examples to answer these questions in the no-BS style that millions of readers have come to expect and love.<br><br>Brown writes, “One of the most important findings of my career is that daring leadership is a collection of four skill sets that are 100 percent teachable, observable, and measurable. It’s learning and unlearning that requires brave work, tough conversations, and showing up with your whole heart. Easy? No. Because choosing courage over comfort is not always our default. Worth it? Always. We want to be brave with our lives and our work. It’s why we’re here.”<br><br>Whether you’ve read <i>Daring Greatly </i>and<i> Rising Strong</i> or you’re new to Brené Brown’s work, this book is for anyone who wants to step up and into brave leadership.

In <i>Originals</i> he again addresses the challenge of improving the world, but now from the perspective of becoming original: choosing to champion novel ideas and values that go against the grain, battle conformity, and buck outdated traditions. How can we originate new ideas, policies, and practices without risking it all?<br>  <br> Using surprising studies and stories spanning business, politics, sports, and entertainment, Grant explores how to recognize a good idea, speak up without getting silenced, build a coalition of allies, choose the right time to act, and manage fear and doubt; how parents and teachers can nurture originality in children; and how leaders can build cultures that welcome dissent. Learn from an entrepreneur who pitches his start-ups by highlighting the reasons not to invest, a woman at Apple who challenged Steve Jobs from three levels below, an analyst who overturned the rule of secrecy at the CIA, a billionaire financial wizard who fires employees for failing to criticize him, and a TV executive who didn’t even work in comedy but saved <i>Seinfeld </i>from the cutting-room floor. The payoff is a set of groundbreaking insights about rejecting conformity and improving the status quo.

Columbus and Donadrian L. Rice have assembled a much-needed collection of Watts's scholarly essays and lectures. Compiled from professional journals, monographs, scholarly books, conferences, and symposia proceedings, the volume sheds valuable light on the developmental arc of Watts's thinking about language and mysticism, Buddhism and Zen, Christianity, comparative religion, psychedelics, and psychology and psychotherapy. This definitive collection challenges Watts's reputation as a "popularizer" or "philosophical entertainer," revealing his concerns to be much more expansive and transdisciplinary than is suggested by the parochial "Zen Buddhist" label commonly affixed to his writings. The editors' authoritative introduction elucidates contemporary perspectives on Watts's life and work, and supports a bold rethinking of his contributions to psychology, philosophy, and religion.
