Once you catch the idea for an extended narration—drama or novel–and if that idea is firmly within you, then the writing brings you perhaps not so much pleasure as a deep absorption. … You see, my wastepaper basket is filled with works that went a quarter through and which turned out to be among those things that failed to engross the whole of me. And then, for a while, there’s a very agonizing period of time in which I try to explore whether the work I’ve rejected cannot be reoriented in such a way as to absorb me. The decision to abandon it is hard.
Thornton Wilder, Playwright, born April 17, 1897–December 7, 1975
