Famous quotes containing the words shared, secret and/or keys:
“But popular rage,
Hysterica passio dragged this quarry down.
None shared our guilt; nor did we play a part
Upon a painted stage when we devoured his heart.”
—William Butler Yeats (1865–1939)
“The secret of a long life is knowing when it’s time to go.”
—Michele Shocked (b. 1962)
“And yet we constantly reclaim some part of that primal spontaneity through the youngest among us, not only through their sorrow and anger but simply through everyday discoveries, life unwrapped. To see a child touch the piano keys for the first time, to watch a small body slice through the surface of the water in a clean dive, is to experience the shock, not of the new, but of the familiar revisited as though it were strange and wonderful.”
—Anna Quindlen (b. 1952)
