If you are unsettled about what you should be doing for a career, maybe you should take an interest in some other professions. 

Talk to people, find out how they like the job, the good and the bad.

It is fairly simple…just walk up to them and say, “I am thinking about becoming a nurse.  Do you have time to talk with me about it?” 

Obviously, this works better if you actually are thinking about becoming a nurse.

Most people are more than happy to talk about their jobs, how they decided on this specific career, and will give you advice on the best path you should take to get there.
