Famous quotes containing the words long, series, drill and/or bits:

    And my youth comes back to me.
    And a verse of a Lapland song
    Is haunting my memory still:
    “A boy’s will is the wind’s will,
    And the thoughts of youth are long, long thoughts.”
    Henry Wadsworth Longfellow (1809–1882)

    Autobiography is only to be trusted when it reveals something disgraceful. A man who gives a good account of himself is probably lying, since any life when viewed from the inside is simply a series of defeats.
    George Orwell (1903–1950)

    Swift blazing flag of the regiment,
    Eagle with crest of red and gold,
    These men were born to drill and die.
    Point for them the virtue of slaughter,
    Make plain to them the excellence of killing
    And a field where a thousand corpses lie.
    Stephen Crane (1871–1900)

    What in fact have I achieved, however much it may seem? Bits and pieces ... trivialities. But here they won’t tolerate anything else, or anything more. If I wanted to take one step in advance of the current views and opinions of the day, that would put paid to any power I have. Do you know what we are ... those of us who count as pillars of society? We are society’s tools, neither more nor less.
    Henrik Ibsen (1828–1906)
