I'm not sure what type of guidance you're looking for, but I depending on where you are in life (high school, college, etc.), you could start looking for volunteer or internship roles in your perspective disciple. Are you interested in law? Contact some local law firms and see if they could use an extra set of hands. Interested in the medical profession? Contact your local hospital to see if there's some volunteering or part-time work you can do. These types of jobs will help you get other jobs and give you hands on experience in your potential career.
Hope this helps!
I think the best place to start would be narrowing down your interests. Then you can focus in on the necessary skills for that career type. Do some research online and see what really interests you.
