Famous quotes containing the word action:
“Perhaps a modern society can remain stable only by eliminating adolescence, by giving its young, from the age of ten, the skills, responsibilities, and rewards of grownups, and opportunities for action in all spheres of life. Adolescence should be a time of useful action, while book learning and scholarship should be a preoccupation of adults.”
—Eric Hoffer (1902–1983)
“We are oft to blame in this,
‘Tis too much proved, that with devotion’s visage
And pious action we do sugar o’er
The devil himself.”
—William Shakespeare (1564–1616)
“Suit the action to the word, the word to the action, with this special observance, that you o’erstep not the modesty of nature.”
—William Shakespeare (1564–1616)
