Three techniques that can be used to apply to selecting a major or career are to brainstorm, invent a major or career, and test your trial choices. these techniques can be used to generate ideas about many aspects of our daily lives.brainstorming is an effective way to approach solving a problem like what career should i choose. once the problem is identified, you can begin to generate solutions. all solutions are laid out on the table. later these ideas can be evaluated and judged. writing these ideas out on paper, on a chalkboard, or on 3x5 cards helps in arranging them at another point. brainstorming with others increases your chances of finding a solution and makes for a more creative exercise. brainstorming can be fun and productive if utilized appropriately.another technique for selecting a major or career is to invent one. it is not necessary to limit majors or careers to course catalogs or job descriptions in the occupational outlook handbook. schools have flexible programs that can be created to combine interests and course of study through independent study or even by combining to majors (or completing a complementary minor to your major course of study).testing your trial choices is an important step when it comes to choosing a major or career. choosing allows you to experiment with courses, visit instructors who teach courses in the major, and talk with people in the field who may have careers in this area. enrolling in a course specific to the major or volunteering, interning or finding part-time employment is another way to find out if the major or career your planning is a good fit for your learning and working style. these experiences may confirm your choice, or let you know valuable information about why this choice may not be right for you.
