A certain man wrote a book entitled,
“HOW TO CHANGE YOUR WIFE IN 30 DAYS,” and it sold more than 30 million copies within a week.
Later on,it was discovered that there was a writing error with the title.
It was supposed to be,
“HOW TO CHANGE YOUR LIFE IN 30 DAYS.”
Well,ever since they corrected the error, not a single book had been sold.
