I love training. It's not just about the competing. I had an amount of natural talent – you need that to go so far – but, actually, what I had, I think, is an ability to make myself work hard, to do the things I didn't like doing, to do the things that I wasn't so good at.

But if I’ve come up with any kind of mantra for myself it’s to try and put myself into a state of imaginative play.

I was very, very thorough, making sure I really understood how that telescope worked, and that it was working properly. I was quite convinced that I wasn't clever enough to be in Cambridge and would be thrown out at some stage. My policy was to work as hard as I could so that I'd know I'd done my best. We now label this as impostor syndrome, but we didn't recognise, and certainly didn't name it, back then.

Of all of the things that I value most about my abilities, intelligence is not top of that list. My ability to endure pain and suffering, my ability to work on something for a very, very long period of time, my ability to handle setbacks and see the opportunity just around the corner I consider to be my superpowers, and I hope they're yours.

Scientists are people who are curious and want to pursue knowledge and pursue truth, and this still remains the most timeless and priceless value of a scientific career. My advice to an early-career scientist is to remain true to your passion and curiosity and that sense of mission to discover knowledge and uncover innovation. It's also very important to be using the tools of the moment, of the century. There are a lot of new tools to uplevel our own scientific research and scientific quest.
