Dedicate Yourself to Learning the History of Sedulous

No fooling—the word sedulous ultimately comes from Latin se dolus, which literally means "without guile." Those two words were eventually melded into one, sedulo, meaning "sincerely" or "diligently," and from that root developed Latin sedulus and English sedulous. Don't let the sed- beginning mislead you; sedulous is not related to words such as sedentary or sedate (those derive from the Latin verb sedēre, meaning "to sit"). Sedulous people are not the sedate or sedentary sort. They're the hardworking types Scottish author Samuel Smiles must have had in mind when he wrote in his 1859 book Self-Help, "Sedulous attention and painstaking industry always mark the true worker."
