Career ChangeA. People who are thinking about changing careers are often afraid of what will happen if they quit their job. Will they find another one? Will they like another field as well as the one they are in now? Will they be able to grow and advance in a new organization?B. As these questions come to mind, they should try to figure out the answers so they can reach a decision. Although there is a high rate of unemployment in some countries, there are usually jobs for skill ed workers who ca use computers or other equipment. Those who have specialized training in these areas can generally find a position without too much effort.C .The question of whether they II like another field more than their current one is also a crucial one. While it s nice to dream about having another job , the reality may be that they arent suited for it. For example , if an architect likes to cook but has no idea about how to run a business , it may be risky for him to open a restaurant. He can cook for his friends on weekends and satisfy his dreams of being a chef in that way.D. Another good way for a person to find out if she will be successful in a new field is to try it out as a part-time job. Being an event planner sounds glamorous but helping friends with parties or weddings might show her that it also very stressful. However, if she has the creativity and organization necessary for such a position , she can continue to plan events for friends until she builds up a reputation. Then she can leave her current job to look for a job in event planning knowing that she ll be successful in this area.E. Once a person has found his or her specialty and decides on the change , it s necessary to stick with it until the business gets off the ground. This usually takes about five years. If the move has been from one company to another, the person should stay until it is clear he is doing a good job and can advance to a higher position. Following this advice will make the transition smoother and the career change successful.For each question , choose the best answer based on the reading sage.
