Acting is such an over-crowded profession（职业）that the only advice that should be given to a young person thinking of going on to the stage（舞台）is "Don't!" But it is useless to try to discourage someone who feels that he must act, although the chances of his becoming famous are slight. The normal way to begin is to go to a drama（戏剧）school. Usually only students who show promise and gift are accepted, and the course lasts two years. Then the young actor or actress takes up work with a theatrical company, usually as an assistant stage manager. This means doing everything that there is to do in the theatre: painting scenery, publicity（宣传）, taking care of the costumes（服装）, and even acting very small parts. It is very hard work indeed, the hours are long and the salary is tiny.

Of course, some people have remarkable chances which lead to fame and success without this long and hard training. Connie Pratt, for example, was just an ordinary girl working in a bicycle factory. A film producer happened to catch sight of her one morning waiting at a bus stop, as he drove past in his car. He stopped and got out to speak to the girl. He asked if she would like to go to the film studio（制片厂）to do a test, and she thought he was joking. Then she got angry and said she would call the police. It took the producer twenty minutes to make Connie believe that he was serious. The test was successful. And within a few weeks she was playing the leading part opposite one of the most famous actors of the day. But chances like this happen once in a blue moon!
