Famous quotes containing the word stroke:
“The one prudence in life is concentration; the one evil is dissipation: and it makes no difference whether our dissipations are coarse or fine; property and its cares, friends and a social habit, or politics, or music, or feasting. Everything is good which takes away one plaything and delusion more, and drives us home to add one stroke of faithful work.”
—Ralph Waldo Emerson (1803–1882)
“Just at the stroke when my veins start and spread,
Set on my soul an everlasting head.
Then am I ready, like a palmer fit,
To tread those blest paths which before I writ.”
—Sir Walter Raleigh (1552?–1618)
“There are no days in life so memorable as those which vibrated to some stroke of the imagination.”
—Ralph Waldo Emerson (1803–1882)
