Conduct a self-assessment. Decide what you really enjoy doing and what you do not like to do.
Determine what skills you have that could be used to make money. If you are able to arrange plants in a garden and make them grow year-round, you might be able to use that skill to earn a living.
Research the economic trends. Determine which industries or fields have a growing need for people. Find out which jobs are being eliminated or outsourced.
Combine the information from your self-assessment with the research you've done on the job market. You can then determine the career path you should follow based on the results.
Research college majors and match them with the results of your self-assessment. Determine which major will help you develop your skills and lead to a career.
