By asking questions about the role and the company, I found a lot of clarity around which company my values aligned to and which role I could find the most passion, growth opportunities, and development from. I highly recommend reaching out to people in the professions you are choosing from and learn from their experience to see if you want to pursue the same kind of work.
If you are deciding between multiple careers, I would recommend doing your research on each. Doing some internet searches to see if you can find interviews with professionals in those industries talking about what their job looks like. Research what amount or level of education will be required for each career. This can be a key piece of information because if you don't love going to school, then something in the medical field may be difficult due to the years of school involved. On the other hand, if a master's degree is required for a certain career, this can help you plan out your next steps.
Another step I would recommend in using LinkedIn to make connections with industry professionals in each field. Take the opportunity to reach out to these individuals and learn more about what they do and what their job entails. Also take the time to learn about the path they took to get to this point in their career. This can be another useful tool when it comes to you having to plan out the next several years of your career.
