Dorothy, what a good problem to have! The best way to narrow down career paths is to TRY them - ask to shadow someone in that profession, do an internship over a summer, ask someone to talk about their job over coffee or lunch. I can't tell you how much I learned from sitting at a coffee shop with someone, talking about their job - it ruled out a lot of paths! Nothing compares to actually experiencing them though, so shadow someone or volunteer at a clinic you're interested in. Hope this helps!
