Businesses put lots of time and money into new plans, programs and excellent employees with the hope things will change. Yet, at the end of the effort, not much changes. What happens? In most cases, those new plans, programs and employees enter a company with an existing culture (文化). And plans, programs and new employees have a way of conforming to(顺应)the existing culture. The culture of your business is the result of a particular mindset , or a particular way of thinking and the general feelings about certain things. Most often, it is the mindset of the founder or people managing the business. The founder has gotten to where he is because of his skill sets, knowledge base and personal beliefs, which unfortunately all come with inherent (固有的)limits. Why? Skills, knowledge and beliefs come from what he or she already knows or has experienced. In other words, it comes from the past. We ( people) try to make the past fit the future. Just because something worked in the past, doesn't mean it is suitable for the future. As the saying goes, if you do and think what you have always done and thought, you will have what you have always had. Therefore, lasting changes have to start with the way people think. To make changes in the way you think, you will be required ta set goals beyond your basic abilities and continuously think them through. It is a way to train yourself and people to get out of the comfort zone where you feel happy with your knowledge and skills. Which question does the author try to answer?
