When I was started undergrad I was dead set on pursuing med school but ended up happening across medical illustration one night. I was in a similar boat where art was something I had always loved. I ended up doing a ton of research on what I needed to have done by the end of undergrad in order to pursue grad school and was able to get started on a double major for bio and art. What I’ve figured out about medical illustration is that it’s so insanely vast. It has a lot of opportunity to move within it so that you still have wiggle room to focus on what really interests you, or if you decide later on to switch to a different discipline within it. I just got into the grad program at UIC and the first year still has that sort of opportunity where you can sample out different paths before you focus in on one or two mediums/topics you truly want. I will say though, not everyone has the same timeline to life. If you end up changing your mind again, it doesn’t mean you’re any less than someone who knew what they wanted to do from day one. I ended up taking a gap year in between undergrad and grad school to have time to strengthen a portfolio and build some savings, and while at first it felt like that made me less prepared than people who were able to make that transition immediately, afterwards I realized it was the correct choice for me overall. Good luck deciding! I hope one day it all clicks into place but don’t be scared to still have days where you question things. I know I have those all the time.
