I'm glad I chose engineering
In hindsight, technology just happened to be one of my many interests when I was younger. Even when deciding which subjects to carry forward at school, I didn't have a clear idea of what I wanted to do for a career. I find this quite scary, and count myself very lucky that I took forward science and maths, and then chose engineering at university.
Now thankfully, whether it's designing electric sports cars in America, measuring ice melt in the arctic, or developing missile defence systems in the Middle East, I don't think I will ever want to work as anything other than an engineer for the rest of my life.
