Famous quotes containing the word time:

    All neighbourly content and easy talk are gone,
    But there’s no good complaining, for money’s rant is on,
    He that’s mounting up must on his neighbour mount
    And we and all the Muses are things of no account.
    They have schooling of their own but I pass their schooling by,
    What can they know that we know that know the time to die?
    William Butler Yeats (1865–1939)
