Choosing a career One of the most important decisions in the life of every person is to choose the right career or occupation. With hundreds jobs to choose from, it’s never too early to begin thinking about your future career. Choosing a career is one of those decisions that can change the course of your life forever. We often speak of full-time jobs or part-time jobs, regular jobs or odd jobs. People may lose their jobs, become unemployed and have to look for new jobs. Different jobs require different things. For example, some require special training and meeting people, others require a good imagination or travelling a lot, physical strength or working late hours… Choosing a career is not easy. A lot of people are encouraged by their teachers, parents and friends. Some people change their minds many times or follow in someone’s footsteps. Others are influenced by certain people or certain events. When you look for a career, you should look carefully at all aspects of the job. You must also take a good look at yourself. What are the ways to make the right choice? 1. _________________________________ Are you a self – starter and do the work on your own, or do you need the discipline of a structured work place to do your best? If you’re naturally a daydreamer or a procrastinator, you may do well in a career where a supervisor helps you stay on task. 2. _________________________________ Do you have a hobby or a talent that you love and are good at? Think of ways to transform activities that come naturally to you into a career. Working with wood, playing an instrument or trying different hairstyles can lead to careers as a furniture maker, a musician or a hair stylist. Doing what you love is a key to a rewarding career. 3. _________________________________ One of your goals should be to choose a career where you can earn enough money to meet your financial goals. If you want to own a vacation home on every continent and fly to these homes on your private jet, a career as a secretary will not help you achieve your goals. 4. _________________________________ You’ll spend one – third of your life with the people you work with, so choose a career that is a good social fit for you. If you’re a loner who doesn’t enjoy social interaction, you’d better work independently or work from home. If you love to meet new people, choose a career which will fulfill your social needs. 5. _________________________________ Find ways to get real – life experience in the kind of place where you want to work. This will help you to decide for certain. Job shadows, internships and temporary assignments give you a realistic view of a day in the life of a profession. 6. _________________________________ And the last one, try to answer the questions: In what school subjects do I get the highest marks? What talents or natural abilities do I seem to have? (talking, writing, singing, painting or taking objects apart and putting them back together) What do I think I could learn to do well? What do other people think I could do? The answers will help you to discover your natural abilities or even talents. Besides, there are special aptitude tests you can take. Careers officers can help and advise young people to get good training in order to have some skills. We live in the computer age. There are about 100 million computers in the world at the moment. You don’t need to be a computer genius to work with a computer but your computer skills need to be good and you have to work on them all the time. Education is important in your future career prospects. A high school graduate has a better chance. Specialized training opens up even more job opportunities. You can get this training in vocational high school, in a college, in vocational-technical school, or through on-the-job training. Task 1. Read the text.
