Career Preparation

Although you may think you are too young to worry about your future career, it is important that you start thinking about your life after high school right now so that you can take the steps necessary to any career you may choose. Some of these steps include choosing the right high school, enrolling in the necessary courses, earning good grades, getting work experience and building a resume. It can seem overwhelming trying to choose a career before you complete high school, but always keep in mind that it is never too late to change your career path and no one says you have to decide now.

 

There are lots of different factors that go into choosing a career path. To determine the occupation you want to enter, you need to consider your interests, how long you want to be in school, how much money you want to make, the type of work you want to do, the potential for job growth and job trends in the industry - sounds like a lot, but that is just the tip of the iceberg.

Each day you make many decisions - what to wear, who to hang out with, how to spend your time after school. Some of the decisions you make today can affect you for the rest of your life. Once you have figured out the things you like to do and the things you do well, you can begin exploring careers that include your interests and skills. Make a plan from the beginning, and once you have a plan, work the plan. Do the steps along the way each year to keep on track toward graduation and higher education.

You may consider a future career now because …………..

A. you have to decide it immediately

B. it is necessary to have preparations

C. you can change your career path

D. you have nothing to worry about
