Everyone has different aptitudes (talent) and interests and you have to figure out what they may be for you. How's your memory, coordination, imagination, etc.? What do you like to do?

No matter what, one has to start at the beginning of a career, at a beginning job. Working takes education and experience and both of those take time. I would find a job in a large company and look around and imagine all that goes into running that company, all the various jobs there are (advertising, accounting, sales, personnel, management, general business administration, legal, transportation, computers, etc.) and try to rotate to different departments and see what interests you most.

If you prefer school to working, you do the same at a large univesity; take classes in as many different areas as you can; math, science, computers, English literature, history, sociology, psychology, education, etc., and see what interests you.

It's all about personal choices. You can work or go to school or do both or start your own business, etc. But no one else can really figure out what you "should" do, everyone is busy trying to figure out what they themselves want to do!
