Famous quotes containing the word precision:
“Some authorities hold that the young ought not to lie at all. That, of course, is putting it rather stronger than necessary; still, while I cannot go quite so far as that, I do maintain, and I believe I am right, that the young ought to be temperate in the use of this great art until practice and experience shall give them that confidence, elegance and precision which alone can make the accomplishment graceful and profitable.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
