Famous quotes containing the words open, cycle and/or closed:
“The secret point of money and power in America is neither the things that money can buy nor power for powers sake ... but absolute personal freedom, mobility, privacy. It is the instinct which drove America to the Pacific, all through the nineteenth century, the desire to be able to find a restaurant open in case you want a sandwich, to be a free agent, live by ones own rules.”
—Joan Didion (b. 1934)
“The lifelong process of caregiving, is the ultimate link between caregivers of all ages. You and I are not just in a phase we will outgrow. This is lifebirth, death, and everything in between.... The care continuum is the cycle of life turning full circle in each of our lives. And what we learn when we spoon-feed our babies will echo in our ears as we feed our parents. The point is not to be done. The point is to be ready to do again.”
—Paula C. Lowe (20th century)
“One mans observation is another mans closed book or flight of fancy.”
—Willard Van Orman Quine (b. 1908)
