Hmmm...that's a tough one. At age 62, I'm still trying to come up with an answer to that. I'm leaning towards "writer," however.... ;-)
As a kid, I went through the usual little-girl phase of nurse, and as I grew older, realized I don't have it in me to stab anyone with a needle, hating needles as much as I do.
Ditto for doctor of any kind, for the same reason--although in my era, a female doctor or veterinarian was nearly unheard of.
Since I grew up playing 'grease monkey' helping my father tinker with the car and make things, I wanted to take auto shop in high school, but was not allowed for no better reason than being female. (Yep--that was before the "women's lib" movement.)
I sucked at math, so any profession requiring higher math was out. Even though I find chemistry and physics fascinating, I don't have the math background for either.
So, here I sit, in the autumn of my life, still trying to decide upon my life's career. So, I focus on enjoying life, and like "FloBe," I consider myself a "Jill of all trades;" master of very few. I live by the line "Carpe Diem," (seize the day), and simply do one day at a time.
