W. H. Auden Quote

Laziness acknowledges the relation of the present to the past but ignores its relation to the future; impatience acknowledge its relation to the future but ignores its relation to the past; neither the lazy nor the impatient man, that is, accepts the present instant in its full reality and so cannot love his neighbour completely.
