Famous quotes containing the words life and/or span:
“I feel my belief in sacrifice and struggle getting stronger. I despise the kind of existence that clings to the miserly trifles of comfort and self-interest. I think that a man should not live beyond the age when he begins to deteriorate, when the flame that lighted the brightest moment of his life has weakened.”
—Fidel Castro (b. 1926)
“A tree that can fill the span of a man’s arms
Grows from a downy tip;
A terrace nine stories high
Rises from hodfuls of earth;
A journey of a thousand miles
Starts from beneath one’s feet.”
—Lao-Tzu (6th century B.C.)
