I went with what came natural to me. Drawing and making objects is as easy as breathing. Was good at math, but really had to work at it.
A few years ago I looked into Med School to see what it would require as far as going back to school. I needed about two years to complete science classes and to go through the application process. And that would mean that I would be in residency in my 50s. Too old to do two 24 hour shifts per week in addition to regular shifts. Nope. I do think, with my hand skills, I could have made a good surgeon.
Have you considered black market organ harvesting? Requires skills but no license.
