I don't really know or remember what I wanted to be. I'm not sure I gave it that much thought? I'm sure at some point I wanted to be something, maybe a vet, probably not a teacher, but I really don't have a strong recollection of really really really wanting to do something.
I didn't even really choose what I am, I was simply good at math and science and it seemed a career I could find a job in and make decent money at.
Now, if the question was about what my dream job now would be...
(Actually, I'm not sure about that, I don't really thrive in high-pressure situations, so a creative *job* with deadlines and stress... I don't think I'd like it - crafting will remain a hobby for me!)
