Famous quotes containing the words practical and/or concerns:
“I favor the policy of economy, not because I wish to save money, but because I wish to save people. The men and women of this country who toil are the ones who bear the cost of the Government. Every dollar that we carelessly waste means that their life will be so much the more meager. Every dollar that we prudently save means that their life will be so much the more abundant. Economy is idealism in its most practical terms.”
—Calvin Coolidge (1872–1933)
“The human heart concerns us more than the poring into microscopes, and is larger than can be measured by the pompous figures of the astronomer.”
—Ralph Waldo Emerson (1803–1882)
