If I had my life again I know what I would do: I’d be an inventor. I can think of nothing more creatively and intellectually rewarding than devising and making wonderful new products. As Nikola Tesla, one of the greatest inventors, said: “I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of his brain unfolding to success . . . Such emotions make a man forget food, sleep, friends, love everything.”
Now it could be argued that one is never too old to switch careers: after all, I’ve dabbled in a few fields over the decades – restaurants, stockbroking, television, healthcare – and even writing for newspapers. But I have always held the view that inventing is a younger person’s game; or at least, a pursuit one should embark upon at a young age.
