Thank you for posting your question. I found myself in the same position as you during the start of my career. I had many interests that I found appealing. I would definitely recommend thinking about things that you love to do. Start asking yourself internal questions; Do you like to help people? Do you enjoy solving problems? Do you like to research? In my experience these are some of the qualities I've encountered when working with psychologists, crime scene investigators, and lawyers. Basically, determine what your core interests, and values are, and compare them to a career field that best is aligned with those areas. From there you will be able deduce what career field will be the best for you. I would strive for something you have passion for, and would give you personal and professional gratification.
