Important Things in the World Have Been Accomplished by People Who Have Kept On Trying When There Seemed To Be No Hope At All

Dale Carnegie? Lee de Forest? Dorothy Carnegie? Apocryphal?

Dear Quote Investigator: Dale Carnegie was a popular author of self-improvement books. He once argued against premature discouragement by asserting that most remarkable achievements had been attained by people who continued to try even when no hope seemed possible. Would you please help me to find a citation?

Quote Investigator: In 1942 Dale Carnegie published a newspaper column about U.S. inventor Lee de Forest who faced numerous technological, financial, and legal obstacles in his career. He eventually obtained success with the creation of the Audion vacuum tube. Lee de Forest’s tale illustrated Carnegie’s point that one should not be easily deterred.
