Famous quotes containing the words trail and/or difficulty:
“The trail of the serpent reaches into all the lucrative professions and practices of man. Each has its own wrongs. Each finds a tender and very intelligent conscience a disqualification for success. Each requires of the practitioner a certain shutting of the eyes, a certain dapperness and compliance, an acceptance of customs, a sequestration from the sentiments of generosity and love, a compromise of private opinion and lofty integrity.”
—Ralph Waldo Emerson (1803–1882)
“To treat a “big” subject in the intensely summarized fashion demanded by an evening’s traffic of the stage when the evening, freely clipped at each end, is reduced to two hours and a half, is a feat of which the difficulty looms large.”
—Henry James (1843–1916)
