Even now, it’s funny how early success always stands out. I clearly remember walking through the airport in Mexico after that first win with Riccardo. I put that achievement right up there with my children being born. That’s a bit naughty of me, I suppose, but in my defence it was something my whole life had been leading up to, from the kid sketching on bits of paper, making models, right up to becoming the person responsible for the design of a racing car that’s won a Formula One championship. I remember thinking, This is one of the best days of my life.
