Famous quotes containing the words energy and/or sources:

    But often the presence of mind and energy of a person remote from the spotlight decide the course of history for centuries to come.
    Stefan Zweig (18811942)

    I count him a great man who inhabits a higher sphere of thought, into which other men rise with labor and difficulty; he has but to open his eyes to see things in a true light, and in large relations; whilst they must make painful corrections, and keep a vigilant eye on many sources of error.
    Ralph Waldo Emerson (1803–1882)
