Famous quotes containing the word growth:
“The risk for a woman who considers her helpless children her “job” is that the children’s growth toward self-sufficiency may be experienced as a refutation of the mother’s indispensability, and she may unconsciously sabotage their growth as a result.”
—Letty Cottin Pogrebin (20th century)
“Sensuality often accelerates the growth of love so much that its roots remain weak and are easily pulled up.”
—Friedrich Nietzsche (1844–1900)
“The Past—the dark unfathom’d retrospect!
The teeming gulf—the sleepers and the shadows!
The past! the infinite greatness of the past!
For what is the present after all but a growth out of the past?”
—Walt Whitman (1819–1892)
