Attend a job fair (you can google it, for something near your area) to see what is out there. Don’t just follow the trend, or whatever your sister / sis-in-law does. Not everyone needs to be a therapist or teacher.
Also, you can google “emerging job trends” or “jobs for the next 10 years” and see what reputable magazines like US News / Fortune / Consumer Reports / Business Week) have to say on the subject.
You might also check with a local college to see if they have a carrear counslor who can tell you what the courses they offer will prepare you for. They might even have a placement office, soyou can get an idea of where the graduates end up.
