ciena 6500 manual pdf: The Code of Trust Robin Dreeke, Cameron Stauth, 2017-08-08 A counterintelligence expert shows readers how to use trust to achieve anything in business and in life. Robin Dreeke is a 28-year veteran of federal service, including the United States Naval Academy, United States Marine Corps. He served most recently as a senior agent in the FBI, with 20 years of experience. He was, until recently, the head of the Counterintelligence Behavioral Analysis Program, where his primary mission was to thwart the efforts of foreign spies, and to recruit American spies. His core approach in this mission was to inspire reasonable, well-founded trust among people who could provide valuable information. The Code of Trust is based on the system Dreeke devised, tested, and implemented during years of field work at the highest levels of national security. Applying his system first to himself, he rose up through federal law enforcement, and then taught his system to law enforcement and military officials throughout the country, and later to private sector clients. The Code of Trust has since elevated executives to leadership, and changed the culture of entire companies, making them happier and more productive, as morale soared. Inspiring trust is not a trick, nor is it an arcane art. It’s an important, character-building endeavor that requires only a sincere desire to be helpful and sensitive, and the ambition to be more successful at work and at home. The Code of Trust is based on 5 simple principles: 1) Suspend Your Ego 2) Be Nonjudgmental 3) Honor Reason 4) Validate Others 5) Be Generous To be successful with this system, a reader needs only the willingness to spend eight to ten hours learning a method of trust-building that took Robin Dreeke almost a lifetime to create. |
ciena 6500 manual pdf: Learning by Heart Tony Wagner, 2021-04-06 “A page turner. With candor and clarity, Tony Wagner tells the story of his remarkable life and, in so doing, tells the story of our education system.” —Angela Duckworth, Founder and CEO, Character Lab, and New York Times bestselling author of Grit One of the world's top experts on education delivers an uplifting memoir on his own personal failures and successes as he sought to become a good learner and teacher. Tony Wagner is an eminent education specialist: he has taught at every grade level from high school through graduate school; worked at Harvard; done significant work for the Bill & Melinda Gates Foundation; and speaks across the country and all over the world. But before he found his success, Wagner was kicked out of middle school, expelled from high school, and dropped out of two colleges. Learning by Heart is his powerful account of his years as a student and teacher. After struggling in both roles, he learned to create meaningful learning experiences despite the constraints of conventional schooling--initially for himself and then for his students--based on understanding each student's real interests and strengthening his or her intrinsic motivations. Wagner's story sheds light on critical issues facing parents and educators today, and reminds us that trial and error, resilience, and respect for the individual, are at the very heart of all teaching and learning. |
