Lauren Oliver said this quote
“ Most of the time - 99 percent of the time - you just don't know how and why the threads are looped together, and that's okay. Do a good thing and something bad happens. Do a bad thing and something good happens. Do nothing and everything explodes. And very, very rarely - by some miracle of chance and coincidence, butterflies beating their wings just so and all the threads hanging together for a minute - you get the chance to do the right thing. ”
