Famous quotes containing the word plans:
“In preparing for battle I have always found that plans are useless, but planning is indispensable.”
—Dwight D. Eisenhower (1890–1969)
“Make your plans for the year in the spring, and your plans for the day early in the morning.”
—Chinese proverb.
“When I heard at the close of the day how my name had been receiv’d
with plaudits in the capitol, still it was not a happy night for me
that follow’d,
And else when I carous’d, or when my plans were accomplish’d,
still I was not happy,
But the day when I rose at dawn from the bed of perfect health,
refresh’d, singing, inhaling the ripe breath of autumn,”
—Walt Whitman (1819–1892)
