Famous quotes containing the words peak and/or load:
“Sleep shall neither night nor day
Hang upon his penthouse lid;
He shall live a man forbid;
Weary sev’n-nights, nine times nine,
Shall he dwindle, peak and pine;
Though his bark cannot be lost,
Yet it shall be tempest-tossed.”
—William Shakespeare (1564–1616)
“The only human beings I have thoroughly admired and respected in the world have been those who carried the load of the world with a smile, and who, in the face of anxieties that would have knocked me clean out, never showed a tremor. Such men and women end by owning us, soul and body, and our allegiance can never be shaken. We are only too glad to be owned. Religion is nothing but this.”
—Henry Brooks Adams (1838–1918)
