     One of the most difficult problems a young person faces is deciding what to do. Some people,

however, from the time they are six years old "know" that they want to be doctors or teachers or

firefighters, but most of us do not get around to making a decision about a job until someone or

something forces us to face the problem.

     Choosing a job takes time, and there are a lot of things you have to think about as you try to

decide what you would like to do. You may find that you will have to take special courses for a

particular kind of work, or you may find out that you will need to get enough knowledge for a

particular job.

     Fortunately, there are a lot of people you can turn to for advice and help in making your decision.

At most schools, there are teachers to give you information about jobs. And you can talk over your

ideas with family members and friends who are always ready to listen and to offer suggestions.
