“If I had two lives, in one life I could invite her to stay at my place, and in the second life I could kick her out. Then I could compare and see which had been the best thing to do. But we only live once. Life's so light. Like an outline we can't ever fill in or correct... make any better. It's frightening".”

“We can never know what we want, because, living only one life, we can neither compare it with our previous lives nor perfect it in our lives to come. [...] 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.”

“Human life occurs only once, and the reason we cannot determine which of our decisions are good and which bad is that in a given situation we can make only one decision; we are not granted a second, third, or fourth life in which to compare various decisions.”

“There is no means of testing which decision is better, because there is no basis for comparison. 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 a 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.”

“We can never know what to want, because, living only one life, we can neither compare it with our previous lives nor perfect it in our lives to come.”

“They [human lives] are composed like music. Guided by his sense of beauty, an individual transforms a fortuitious occurrence (Beethoven’s music, death under a train) into a motif, which then assumes a permanent place in the composition of the individual’s life. Anna could have chosen another way to take her life. But the motif of death and the railway station, unfortettably bound to the birth of love, enticed her in her hour of despair with its dark beauty. Without realizing it, the individual composes his life according to the laws of beauty even in times of greatest distress.”

“If we have only one life to live, we might as well not have lived at all.”
