Can anyone help me decide which would be the best career for my future?

Just do what makes you happy. I have a friend who is a social worker and she doesn't make a lot of money but she enjoys what she does. I also had an aunt that was a doctor and hated every part of her job. She was miserable. Moral of this response...do what makes you happy. If you enjoy what you do, you'll never work a day in your life.
