The comfort zone is our living, work, and social environments that we have grown accustomed to. It determines the type of friends we make or people we associate with. It determines a life style we accept or reject.Young people are very adaptable; they can adjust to changing comfort zones with ease. They can socialize with homeless people in the morning and be equally at ease at a formal banquet in the evening. As we age, the ability to adapt to wide-ranging comfort zones becomes more difficult. Social prejudice narrows the comfort zone range. The comfort zone can be a decision making tool.Comfort zones are directly related to our dreams or goals, which is associate with self-fulfilling prophecy (预言). In order to grow and change, we must firstbe discontent with our current comfort zone. We must realize that all meaningful and lasting changes occur first in daydreaming and then they work their way into reality. The more clearly and vividly we fantasize our dream, the stronger and more real the pictures on the subconscious level will become. Once our subconscious accepts this image and its expectation, it will go to work, searching for a way to bring the dream into reality. If we feel that these things are too good for us, we will find ways to fail. If, however, we intentionally imagine the change we want, build an expectation of the change mentally and emotionally, and we will find ways to acquire dream and, when mentally ready, it will arrive faster than we ever thought possible.For some people, problems, suffering, poverty, bad breaks are their comfort zone. They find comfort in finding fault and complaining about their misfortune. The same is true for businesses. Management and workers have grown used to seeing things go wrong and expect them too. Management finds comfort in finding fault with workers and vice versa.Note if the comfort zone we are seeking is beyond our current income, then, we need to develop a service that has greater value than our current one. Money, power and influence are not goals; they are rewards only for personal achievement.
A．requires a clear goal in mindB．does little good to the pursuit of happinessC．prepares us for meaningful changes in lifeD．wastes our time and energy
