     Acting is such an overcrowded profession that the only advice that should be given to a young person

thinking of going on the stage 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 small.The normal way to begin is to go to a

drama school.Usually only students who show promise and talent are accepted,and the course lasts two

years.Then the young actor or actress takes up work with a play company,usually as an assistant stage

manager.This means doing everything that there is to do in the theatre:painting scenery, publicity,looking

after the furniture,taking care of the clothes,and even acting in very small parts.It is very hard work indeed;

the hours are long and the salary is tiny.But young actors with the stage in their blood are happy,waiting

for the chance of working with a better company,or perhaps in films or television.

     Of course,some people have unusual 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 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 convince Connie that he was serious.Then an appointment was made for her to go to

the company the next day.The test was successful.And within a few weeks she was playing the leading

part in a film.But chances like this happen once in a blue moon!
