Famous quotes containing the words list of, list and/or commands:
“Love’s boat has been shattered against the life of everyday. You and I are quits, and it’s useless to draw up a list of mutual hurts, sorrows, and pains.”
—Vladimir Mayakovsky (1893–1930)
“All is possible,
Who so list believe;
Trust therefore first, and after preve,
As men wed ladies by license and leave,
All is possible.”
—Sir Thomas Wyatt (1503?–1542)
“If writers were too wise, perhaps no books would get written at all. It might be better to ask yourself “Why?” afterwards than before. Anyway, the force from somewhere in Space which commands you to write in the first place, gives you no choice. You take up the pen when you are told, and write what is commanded. There is no agony like bearing an untold story inside you.”
—Zora Neale Hurston (1891–1960)
