"Suddenly you become a public figure being asked to do all sorts of things: to give lectures, quite often on topics you know little about; to sit on committees and reviews you are not always well qualified to be on; to visit countries you have barely heard of; to sign endless petitions on what are probably good causes, but you never know. It is like having a whole new extra job, with upwards of 500 requests a year. It is impostor syndrome on steroids."
