“If you're going through hell, keep going.”
True origin unknown. Finest Hour described it as "not verifiable in any of the 50 million published words by and about him" ( Finest Hour, The Journal of Winston Churchill, Number 145, Winter 2009–10, p. 9 https://www.winstonchurchill.org/images/finesthour/vol.01%20no.145.pdf). A similar quotation: "If you're going through hell, don't stop!" is "plausibly attributed" to Oregon self-help author and counselor Douglas Bloch (1990), according to Quote Investigator.
