Try not to think in absolutes, you don't necessarily have to know what career you want right now, Personally, I find that overwhelming. Instead, try thinking about some general job characteristics. Do you prefer to work with people or alone? Do you want physical activity to be part of your work, or would you prefer a more sedentary job? Are you more comfortable with steady income, or are you open to a little more risk? Knowing yourself is key to knowing what you will be happy doing for a career, and that is a lifelong process. You will make changes and refine your path throughout your life. Don't let not knowing what you want to do keep you from doing because experiences can show us things we wouldn't be able to see any other way.
Think about what you are interested in, or what you are good at in life. If you are in school, think about the classes that you enjoy taking, and the ones that you do well in. If you school has a career counselor, you should try and talk to him/her for advice.
I understand EXACTLY what you are going through. There's a lot out there and where to start. You should start by asking your own self what you like and enjoy! And the answer to the previous question should be where you should start looking! It only makes sense to me because if you hate everything about the medical field you probably don't want to roll out of bed ever morning and tell yourself "I need to be a doctor AGAIN today". So with that in mind what do like or enjoy for activities? And see what is related to that! And try to narrow things down from there!
If I were you, I would ask myself, what are the things I enjoy, also what are you good at doing? Are you good in math/science or are you more of a history buff and English. Are you good with people or do you do better with dealing with a phone and computer all day.
Go directly to your college career guidance and counseling center. Take some online career interest inventories. Work with someone FREE on campus to narrow down your interests.
Realize that most people today will have 1-5 related careers in their lifetime. YOU want something that has employment potential, you enjoy, and good earning potential.
You'll get there. We've all been through this process unless your one of the few who "knew" exactly what they wanted at an early age.
