All human errors are impatience, the premature breaking off of what is methodical, an apparent fencing in of the apparent thing.

[Alle menschlichen Fehler sind Ungeduld, ein vorzeitiges Abbrechen des Methodischen, ein scheinbares Einpfählen der scheinbaren Sache.]

Franz Kafka (1883-1924) Czech-Austrian Jewish writer

Alt. trans.: "All human errors are impatience, a premature breaking off of methodical procedure, an apparent fencing-in of what is apparently at issue."
