Famous quotes containing the words option, difference and/or samples:
“You don’t merely give over your creativity to making a film—you give over your life! In theatre, by contrast, you live these two rather strange lives simultaneously; you have no option but to confront the mould on last night’s washing-up.”
—Daniel Day Lewis (b. 1957)
“Friends serve central functions for children that parents do not, and they play a critical role in shaping children’s social skills and their sense of identity. . . . The difference between a child with close friendships and a child who wants to make friends but is unable to can be the difference between a child who is happy and a child who is distressed in one large area of life.”
—Zick Rubin (20th century)
“Good government cannot be found on the bargain-counter. We have seen samples of bargain-counter government in the past when low tax rates were secured by increasing the bonded debt for current expenses or refusing to keep our institutions up to the standard in repairs, extensions, equipment, and accommodations. I refuse, and the Republican Party refuses, to endorse that method of sham and shoddy economy.”
—Calvin Coolidge (1872–1933)
