Famous quotes containing the words common and/or designs:
“Down these mean streets a man must go who is not himself mean, who is neither tarnished nor afraid.... He is the hero, he is everything. He must be a complete man and a common man and yet an unusual man. He must be, to use a rather weathered phrase, a man of honor, by instinct, by inevitability, without thought of it, and certainly without saying it. He must be the best man in his world and a good enough man for any world.”
—Raymond Chandler (1888–1959)
“My own thoughts
Are my companions; my designs and labors
And aspirations are my only friends.”
—Henry Wadsworth Longfellow (1807–1882)
