We live everything as it comes, without warning, like an actor going on cold. And what can life be worth if the first rehearsal for life is life itself? That is why life is always like a sketch.

No, “sketch” is not quite the word, because a sketch is an outline of something, the groundwork for a picture, whereas the sketch that is our life is a sketch for nothing, an outline with no picture.

Einmal ist keinmal, says Tomas to himself. What happen but once, says the German adage.
