Famous quotes containing the words productive and/or behavior:
“Youth is disagreeable time, for it is neither possible then nor prudent to be productive in any sense whatsoever.”
—Friedrich Nietzsche (1844–1900)
“The fact that behavior is “normal,” or consistent with childhood development, does not necessarily make it desirable or acceptable...Undesirable impulses do not have to be embraces as something good in order to be accepted as normal. Neither does children’s behavior that is unacceptable have to be condemned as “bad,” in order to bring it under control.”
—Elaine Heffner (20th century)
