Famous quotes containing the words energy and/or balance:
“The principle of avoiding the unnecessary expenditure of energy has enabled the species to survive in a world full of stimuli; but it prevents the survival of the aristocracy.”
—Rebecca West (1892–1983)
“... idleness is an evil. I don’t think man can maintain his balance or sanity in idleness. Human beings must work to create some coherence. You do it only through work and through love. And you can only count on work.”
