     It is said that there are about 40,000 different kinds of jobs in the world.    1   

     "Finding a job" is not the same as "choosing a job". Many young people end up in a job which they

are not suitable for.    2   . Here are a few steps to help you think about jobs which you might enjoy

doing after school or university.

     First, it is important to realize what kind of person you are, which special qualities make you different

from everyone else and what you are interested in.    3   . If you like art and enjoy looking at pictures,

that is an interest. But if you can draw a horse that looks like a horse instead of a big dog, that is a skill.

     Then ask yourself this question: in the following three areas ? skills with people, skills with information

and skills with things ? which are your best skills?

     After examining your skills, the next step is research. To find out as many different kinds of jobs as

possible, go to the library and read books, magazines and newspapers.    4   

     Finally, trust your own ideas and your own thinking!    5  

A. It is your own life, so find something that you enjoy doing.

B. Choosing the right one itself is a difficult job.

C. We must know what our ideal jobs are.

D. There is a difference between an interest and a skill.

E.  Ask your friends about the work they do.

F. "Chance" may play a more important part than "decision"

G. Your parents may also give you some useful advice.
