常识告诉我们，你总是可以选择你对待事件的反应。 但是，正如企业顾问Stephen Klemich和临床心理学家Mara Klemich所主张的那样，除非你意识到自己为什么要做出选择，以及内心和大脑如何共同塑造你的行为，否则你根本无法改变根深蒂固的行为模式，这也就是为什么人们总是会重复自己犯过的错误和消极的行为。本书对此进行了深入的探讨并提出改变的可行办法，让你可以对自己和周围做的世界出积极的影响。 A leadership consultant and neuropsychologist identify the universal habits of the heart and mind—the keys to unlocking our true potential, creating our best selves and?eliminating behavior patterns that hold us back.?Why is it so hard for leaders to coach employees who are struggling? Why do we repeat the same mistakes and negative behaviors? Common wisdom says you always have a choice in how you react or respond. But, as corporate consultant Stephen Klemich and clinical psychologist Mara Klemich contend, until you recognize why you make choices, and how the heart and the brain work together to shape your behavior, you can’t change long-ingrained patterns and discover your best self.The Klemichs have developed a model backed by extensive research and data, and paired it with character-led personal development, to help you answer the "Why?" and eliminate behavior that is “below the line.” In Above the Line, they argue that that the quality of your life flows from the attitudes of your heart. Offering wise, compassionate, and practical advice, this book explores the deep, fundamental drivers of human behavior that exist within your heart—the seat of your character. It reveals that all of these behaviors can be explained by four principles—humility, love, pride, and fear—which influence every facet of your life, for better or for worse.We are all designed for greatness, but so often our best self is pitted against our worst. The pressures of life are pulling our character below the line while our authentic self is drawing us to live above the line. When you fully understand that the four principles are at the root of your behavior, you can begin the journey to become your best self and navigate life more effectively and successfully. Filled with proven strategies, Above the Line will create lasting changes in your behavior and improve your life personally and professionally—so you can make a positive impact on the world around you.

女性陷入了一个困境：要友善，但不能太友善，要成功，但不能太成功，无论如何，必须招人喜欢。而这一点，阻碍了女性成功的协商薪资、要求升职和工作态度强硬，因为这些总会让人不那么受人喜爱。本书深入探讨了这一偏见和束缚，并提供了现实的办法来帮助解决这个阻碍。 Be nice, but not too nice. Be successful, but not too successful. Just be likeable. Whatever that means?Women are stuck in an impossible bind. At work, strong women are criticized for being cold, and warm women are seen as pushovers. An award-winning journalist examines this fundamental paradox and empowers readers to let go of old rules and reimagine leadership rather than reinventing themselves.Consider that even competent women must appear likeable to successfully negotiate a salary, ask for a promotion, or take credit for a job well done—and that studies show these actions usually make them less likeable. And this minefield is doubly loaded when likeability intersects with race, ethnicity, sexual orientation, and parental status. Relying on extensive research and interviews, and carefully examined personal experience, The Likeability Trap delivers an essential examination of the pressure put on women to be amiable at work, home, and in the public sphere, and explores the price women pay for internalizing those demands. Rather than advising readers to make themselves likeable, Menendez empowers them to examine how they perceive themselves and others and explores how the concept of likeability is riddled with cultural biases. Our demands for likeability, she argues, hinder everyone’s progress and power.Inspiring, thoughtful and often funny, The Likeability Trap proposes surprising, practical solutions for confronting the cultural patterns holding us back, encourages us to value unique talents and styles instead of muting them, and to remember that while likeability is part of the game, it will not break you.

From the New York Times bestselling author of The Plant Paradox comes a guide to one-pot cooking for the whole family, with a special focus how to make the Plant Paradox program kid-friendly.Since the publication of The Plant Paradox in 2017, hundreds of thousands of people have embraced Dr. Gundry’s nutritional protocol—and experienced life-changing results. But most of Dr. Gundry’s readers aren’t cooking for themselves alone. “How can I extend this way of eating to my entire family? And is it safe for my kids?” are the questions he is most often asked.In The Plant Paradox Family Cookbook, Dr. Gundry reassures parents as he sets the record straight, providing an overview of children’s nutritional needs and explaining how we can help our kids thrive on the Plant Paradox program—a diet low in lectins. Dr. Gundry offers shocking evidence of how the Plant Paradox program is not only “safe” for kids, but also the best possible way to set them up for a lifetime of health and responsible eating. As research continues to bear out, a healthy microbiome—or “gut”—is the cornerstone of human health. The foods we eat at the beginning of our lives have a long-term impact on the makeup of our microbiome. Lectin-containing foods—such as grains, legumes, certain fruits and vegetables, and conventional dairy—damage it by creating holes in the gut wall and triggering the kind of systemic inflammation that lays the groundwork for disease. And yet, many of the foods we are routinely told to feed our children—think milk, whole grain bread, peanut butter—have an incredibly high lectin content.The Plant Paradox Family Cookbook includes more than 80 recipes that make cooking for a family a breeze. And since pressure cooking is the best and easiest way to reduce lectin content in foods like grains and beans, the majority of the quick and easy recipes are Instant-Pot friendly. From weeknight dinners to make-ahead breakfasts to snacks and even lunchbox-ready meals, The Plant Paradox Family Cookbook will help the whole family experience the incredible benefits of the Plant Paradox program.

From “one of the greatest writers of our time” (Toni Morrison)—the author of Barracoon and Their Eyes Were Watching God—a collection of remarkable stories, including eight “lost” Harlem Renaissance tales now available to a wide audience for the first time. New York Times’ Books to Watch forBuzzfeed’s Most Anticipated Books of 2020Newsweek’s Most Anticipated BooksForbes.com’s Most Anticipated Books of 2020E!’s Top 2020 Books to ReadGlamour’s Best Books In 1925, Barnard student Zora Neale Hurston—the sole black student at the college—was living in New York, “desperately striving for a toe-hold on the world.” During this period, she began writing short works that captured the zeitgeist of African American life and transformed her into one of the central figures of the Harlem Renaissance. Nearly a century later, this singular talent is recognized as one of the most influential and revered American artists of the modern period.Hitting a Straight Lick with a Crooked Stick is an outstanding collection of stories about love and migration, gender and class, racism and sexism that proudly reflect African American folk culture. Brought together for the first time in one volume, they include eight of Hurston’s “lost” Harlem stories, which were found in forgotten periodicals and archives. These stories challenge conceptions of Hurston as an author of rural fiction and include gems that flash with her biting, satiric humor, as well as more serious tales reflective of the cultural currents of Hurston’s world. All are timeless classics that enrich our understanding and appreciation of this exceptional writer’s voice and her contributions to America’s literary traditions.

“With each new book by Tessa Hadley, I grow more convinced that she’s one of the greatest stylists alive.”—Ron Charles, Washington PostNew York Times Book Review Editors' Choice |A Parnassus First Editions Club Pick | Powell’s Indispensable Book Club Pick | A Washington Post Notable Book | A Slate Best Book of the Year | A Boston Globe Best Book of the Year | A Bookpage Best Book of the YearThe lives of two close-knit couples are irrevocably changed by an untimely death in the latest from Tessa Hadley, the acclaimed novelist and short story master who “recruits admirers with each book” (Hilary Mantel).Alexandr and Christine and Zachary and Lydia have been friends since they first met in their twenties. Thirty years later, Alex and Christine are spending a leisurely summer’s evening at home when they receive a call from a distraught Lydia: she is at the hospital. Zach is dead.In the wake of this profound loss, the three friends find themselves unmoored; all agree that Zach, with his generous, grounded spirit, was the irreplaceable one they couldn’t afford to lose. Inconsolable, Lydia moves in with Alex and Christine. But instead of loss bringing them closer, the three of them find over the following months that it warps their relationships, as old entanglements and grievances rise from the past, and love and sorrow give way to anger and bitterness.Late in the Day explores the complex webs at the center of our most intimate relationships, to expose how, beneath the seemingly dependable arrangements we make for our lives, lie infinite alternate configurations. Ingeniously moving between past and present and through the intricacies of her characters’ thoughts and interactions, Tessa Hadley once again “crystallizes the atmosphere of ordinary life in prose somehow miraculous and natural” (Washington Post).

Patricia MacLachlan, beloved author of the Newbery Medal-winning Sarah, Plain and Tall, has crafted another lyrical and touching novel for young readers about finding hope after the loss of a loved one.Declan O’Brien always had a gentle word to share, odd phrases he liked to repeat, and songs to sing while he played basketball. His favorite song was "Dona Nobis Pacem," “Grant Us Peace.” His family loved him deeply and always knew they were loved in return.But a terrible accident one day changes their lives forever, and Fiona and Finn O’Brien are left without a father. Their mother is at a loss. What words are there to guide them through such overwhelming grief?At the suggestion of their friend Luke, Fiona and Finn volunteer at an animal rescue shelter, where they meet two sweet dogs who are in need of comfort, too. Perhaps with time, patience, and their father’s gentle words in their hearts, hope will spark once more.* Junior Library Guild Selection * Bank Street Best Children's Book of the Year 2019 (9-12) *
