What should you think about in trying tofind your career? You are probably better at some school subjects than others.These may show strengths that you can use in your work. A boy who is good atmathematics can use that in an engineering career. A girl who spells well andlikes English may be good at office work. So it is important to know thesubjects you do well in at school. On the other hand, you may not have anyspecially strong or weak subjects but your records show a general satisfactorystandard. Although not all subjects can be used directly in a job, they mayhave indirect value. A knowledge of history is not required for most jobs butif history is one of your good subjects you will have learned to remember factsand details. This is an ability that can be useful in many jobs.
Your school may have taught you skills,such as typing or technical drawing, which you can use in your work. You may begood at metal work or cookery and look for a job where you can improve theseskills.
If you have had a part-time job onSaturdays or in the summer, think what you gained from it. If nothing else, youmay have learned how to get to work on time, to follow instructions and to geton with older workers. You may have learned to give correct change in a shop,for example. Just as important, you may become interested in a particularindustry or career you see from the inside in a part-time job. Facing your weakpoints is also part of knowing yourself. You may be all thumbs when you handletools; perhaps you are a poor speller or cannot add up a column of figures. Itis bitter to face any weaknesses than to pretend they do not exist. Your schoolrecord, for instance, may not be too good, yet it is an important part of yourbackground. You should not be apologetic about it but instead recognize thatyou will have a chance of a fresh start at work.

A.choosing a career according to what oneis skilled in
