Why can habit be regarded as the driving force of high performance in Salesmanship ? The reason is that human beings are creatures of habit. Fully 95 percent of our behaviors are habitual, or occur in response to strong external stimuli. Spontaneity often results from reaction from a given stimulus. High performers can complete tasks at ease by transforming their expertise into reflective behaviors that’s created by subconscious habits. In this article, we use real-world examples of good habits from four outstanding financial managers and divide these habits into five categories: performance management, customer management, time management, stress management, and career management. These managers are Peng, Ching-Yu, the Marketing Director of Cathay Life insurance in Hsinchu branch; Chen, Hung-chang, the customer relationship manager of Taishin International Bank; and other two super-salesmen. Based on semi-structured, in-depth interviews, analysis, and application of Habitual Domains theory, the 30 Magazine’s April 2012 issue concluded that the success of these managers was indeed due to their rich habitual domains. Others can learn from them by developing good habits to expand their own business capability, thereby improving the overall economic competitiveness of Taiwan.
