Nope, I didn’t even think about careers all the way until the final year of my undergraduate degree. I was interested in science and technology since early childhood, sure, but turning that into a career didn’t occur to me until much later.
Kind-of. I thought that I wanted to be a meteorologist (a weatherman), and discovered that the way to be able to do that was to study Physics. Once I was at university, I realised that I was more interested in light and lasers, and that’s where my career has taken me.
In primary school I wanted to be a doctor or an architect. When it came to choosing GCSEs it was either doctor or marine biologist (I’d realised architecture needs a lot more maths than I was happy with). So I guess the answer is “yes”, but it’s never too late to change your mind.
I don’t think I really thought about what I wanted to do! I didn’t really understand what it meant to be a scientist until I was working on my Masters research project. I just kept choosing options that I thought were interesting and the rest took care of itself!
