Famous quotes containing the word key:
“Japanese mothers credit “effort” as the key determinant of a child’s achievement in school, while American mothers name “ability” as the more important factor.”
—Perry Garfinkel (20th century)
“There are two kinds of timidity—timidity of mind, and timidity of the nerves; physical timidity, and moral timidity. Each is independent of the other. The body may be frightened and quake while the mind remains calm and bold, and vice versë. This is the key to many eccentricities of conduct. When both kinds meet in the same man he will be good for nothing all his life.”
—Honoré De Balzac (1799–1850)
“Woe to you lawyers! For you have taken away the key of knowledge; you did not enter yourselves, and you hindered those who were entering.”
—Bible: New Testament, Luke 11:52.
