I'm writing my challenge secondary essay right now and the main challenge I wanted to write about is how when I was growing up and even in high school, I struggled a lot with my motor skills, to the point that tying my shoes as a young kid was hard. I improved a lot because I just kept practicing fine motor movements and now I don't really have any problems as I'm able to run tests on patients just fine for my research, some of which do require pretty fine dexterity as one requires attaching electrodes in the right place for neurostimulation. However, I've been reading that you shouldn't mention mental illness as a challenge because it can turn off adcom's and I was wondering if they could feel the same way about my former issues with my motor skills, as I don't want them to think that I would be a burden to have in a medical school class. Reading the technical standards on the secondary applications I definitely feel that I would be able to complete them as I really don't have any issues with my motor skills at the moment. Can anyone comment if this would be a potential red flag? Thanks!
