Nesnesitelná lehkost bytí (The Unbearable Lightness of Being)

"Einmal ist Keinmal"("once is never", i.e., "what happened once might as well have never happened at all").

Therefore, each life is ultimately insignificant; every decision ultimately does not matter. Since decisions do not matter, they are "light": they do not tie us down. But at the same time, the insignificance of our decisions - our lives, or being - is unbearable.

- Milan Kundera in 1982
