Well, even though I still have my doubts every so often, I think the decision was solidified when I chose my masters degree. I had little idea what kind of real world application of physics I would actually enjoy doing as a job, so when I found out about medical physics I think I finally thought: “This is how I want to spend my time”.
I was around 19 or 20 when I made that decision. But I think it’s perfectly normal to get well past university level without knowing 100% what you want to do with your life.
I can’t really remember when exactly. When I was really young, I saw the guys coming to collect the bins from the street, and I was amazed by the truck, with its mechanical arm, so when my mum asked what I wanted to be, I said ‘a bin man’. When I got a bit older, maybe 9 or 10, I was still facinated with machines and loved finding out how things worked, so I suppose I’ve wanted to be a scientist for as long as I remember.
Not very young Jessica, to be honest!
I have discovered science quite late (I was 15) and I thought I would like to be a science teacher, but only at University, when I was 23, that I have discovered research and I have fallen in love with!
So you see, it’s never too late to get into science.
