Impatience and Indolence
There are two main human sins, from which all the others derive: impatience and indolence. It was because of impatience that they were expelled from paradise; it is because of indolence that they do not return. Yet perhaps there is only one major sin: impatience. Because of impatience they were expelled, because of impatience they do not return.
Franz Kafka, in 'The Zurau Aphorisms (3)'
