Still reading. From what I have read so far and what I have been told, this really is the definitive basis and should be in the knowledge base and library of any serious student of this subject. I have read most of the newer important writings and I still am finding this to be quite worthy of my time. If you are on the fence, I recommend waiting for a decent deal and then making the purchase.

“Volunteers are driven by completely different motives than employees are,” Denburg explained. “I had a habit of rolling in and expecting people to keep up and jump into action. With this job, I had to learn to be more intentional about setting the stage to engage people.” She made the shift from leading through accountability and authority to leading through influence.
To achieve fast results, many popular executive coaches model their interventions after those used by sports coaches, employing techniques that reject out of hand any introspective process that can take time and cause “paralysis by analysis.” The idea that an executive coach can help employees improve performance quickly is a great selling point to CEOs, who put the bottom line first. Yet that approach tends to gloss over any unconscious conflict the employee might have. This can have disastrous consequences for the company in the long term and can exacerbate the psychological damage to the person targeted for help.
Cognitive behavioural hypnotherapy (CBH) is an integrated psychological therapy employing clinical hypnosis and cognitive behavioural therapy (CBT).[14] The use of CBT in conjunction with hypnotherapy may result in greater treatment effectiveness. A meta-analysis of eight different researches revealed "a 70% greater improvement" for patients undergoing an integrated treatment to those using CBT only.[15]
Improvements that stem directly from coaching engagements include: enhanced executive learning, gains in corporate performance, enhanced relationships, increased leadership effectiveness and personal and organizational improvements. In the process, not only do executives improve themselves but substantially have a greater impact on their organization. Benefits to the organization include enhanced individual and organizational performance which positively affect organizational culture. These further provide enhanced reputation within the industry, improved employee morale, and positive work environments, thus greater productivity and enhanced client relationships. Coaching can be your competitive edge!
Coleman Griffith worked as an American professor of educational psychology at the University of Illinois where he first performed comprehensive research and applied sport psychology. He performed causal studies on vision and attention of basketball and soccer players, and was interested in their reaction times, muscular tension and relaxation, and mental awareness.[11] Griffith began his work in 1925 studying the psychology of sport at the University of Illinois funded by the Research in Athletics Laboratory.[12] Until the laboratory's closing in 1932, he conducted research and practiced sport psychology in the field. The laboratory was used for the study of sports psychology; where different factors that influence athletic performance and the physiological and psychological requirements of sport competitions were investigated. He then transmitted his findings to coaches, and helped advance the knowledge of psychology and physiology on sports performance. Griffith also published two major works during this time: The Psychology of Coaching (1926) and The Psychology of Athletics (1928). Coleman Griffith was also the first person to describe the job of sports psychologists and talk about the main tasks that they should be capable of carrying out. He mentioned this in his work “Psychology and its relation to athletic competition”, which was published in 1925.[13] One of the tasks was to teach the younger and unskilled coaches the psychological principles that were used by the more successful and experienced coaches. The other task was to adapt psychological knowledge to sport, and the last task was to use the scientific method and the laboratory for the purpose of discovering new facts and principles that can aid other professionals in the domain.
Being able to focus one’s awareness on relevant cues so they can deal effectively with their current situation. These skills help them maintain their mental intensity within a situation.

"Coaching works when it's systematic," says Babson's Hunt, and many organizations use coaching as an integrated part of a larger leadership development program. Increasingly, firms incorporate "360-degree" feedback, using the results to indicate areas in which an executive might benefit from working with a coach. Has your feedback revealed an area in which you would like to improve? Is it a skill you need to refine in order to advance through the organization? Would you benefit from an outside perspective? The answers to these questions help gauge the potential value of coaching.

Although there are different techniques, clinical hypnotherapy is generally performed in a calm, therapeutic environment. The therapist will guide you into a relaxed, focused state and ask you to think about experiences and situations in positive ways that can help you change the way you think and behave. Unlike some dramatic portrayals of hypnosis in movies, books, or on stage, you will not be unconscious, asleep, or in any way out of control of yourself. You will hear the therapist’s suggestions, but it is up to you to decide whether or not to act on them.
