Our energy is in proportion to the resistance it meets. We attempt nothing great but from a sense of the difficulties we have to encounter, we persevere in nothing great but from a pride in overcoming them.
William HazlittNo wise man can have a contempt for the prejudices of others; and he should even stand in a certain awe of his own, as if they were aged parents and monitors. They may in the end prove wiser than he.
William Hazlitt
