Famous quotes containing the words task and/or priority:

    Now the hungry lion roars,
    And the wolf behowls the moon;
    Whilst the heavy ploughman snores,
    All with weary task fordone.
    Now the wasted brands do glow,
    Whilst the screech-owl, screeching loud,
    Puts the wretch that lies in woe
    In remembrance of a shroud.

    That the graves, all gaping wide,
    Every one lets forth his sprite,
    In the church-way paths to glide:
    William Shakespeare (1564–1616)
