Criticism

Colonel George Washington Goethals, the man responsible for the completion of the Panama Canal, had big problems with the climate and the geography. But his biggest challenge was the growing criticism back home from those who predicted he'd never finish the project.
Finally, a colleague asked him, “Aren't you going to answer these critics?"
"In time," answered Goethals.
"When?" his partner asked.
"When the canal is finished."
