Famous quotes containing the word obstacles:

    It still holds true that man is most uniquely human when he turns obstacles into opportunities.
    Eric Hoffer (1902–1983)

    To ask strength not to express itself as strength, not to be a will to dominate, a will to subjugate, a will to become master, a thirst for enemies and obstacles and triumphant celebrations, is just as absurd as to ask weakness to express itself as strength.
    Friedrich Nietzsche (1844–1900)

    It is very rare that you meet with obstacles in this world which the humblest man has not faculties to surmount. It is true we may come to a perpendicular precipice, but we need not jump off, nor run our heads against it. A man may jump down his own cellar stairs, or dash his brains out against his chimney, if he is mad.
    Henry David Thoreau (1817–1862)
