J. R. R. Tolkien, The Fellowship of the Ring, spoken by Elrond quotes
"He should not vow to walk in the dark, who has not seen the nightfall."
One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man.
Optimism is a kind of heart stimulant--the digitalis of failure.
"He should not vow to walk in the dark, who has not seen the nightfall."
