Julio Cortázar said this quote

“ We know that attention acts as a lightning rod. Merely by concentrating on something one causes endless analogies to collect around it, even penetrate the boundaries of the subject itself: an experience that we call coincidence, serendipity – the terminology is extensive. My experience has been that in these circular travels what is really significant surrounds a central absence, an absence that, paradoxically, is the text being written or to be written. ”
