Good bump!
Career wise, I wanted to be a airplane pilot, but by age 12 I switched to Engineer. The flavor of engineer changed over the years, but I still reached the point of graduating as an engineer. So, mission accomplished?
Odd how I gravitated to math and science and had clear direction at a relatively young age...and stuck with it. I don't know many of my peers with such early clarity and unfailing drive. I will admit, after a decade or so of engineering, I switched to project management as I felt I needed broader exposure and challenges.
