- 2020, Barack Obama, chapter 10, in Chicca Galli, Paolo Lucca, Giuseppe Maugeri, transl., Una terra promessa [A Promised Land], Garzanti Libri:
  ... insistevo nel dire che, prima di migliorare, l'economia sarebbe peggiorata, ricordavo alla gente che la riforma del sistema sanitario non poteva essere realizzata dall'oggi al domani, e che non c'erano soluzioni semplici per posti come l'Afghanistan.
  ... insisting that the economy would get worse before it got better, reminding people that reforming healthcare couldn't happen overnight and that there were no simple solutions in places like Afghanistan.
  (literally, “... I insisted in saying that, before improving, the economy would have worsened, I reminded people that reforming the healthcare system could not be realized overnight, and that there were no simple solutions for places like Afghanistan.”)
