有本書，名叫
《How to change your wife in 30 days》，
一個星期之內售出200萬本。
直到作者發現，書名拼寫錯誤，
正確的應該是：
《How to change your life in 30 days》。
改正後整整一星期，只賣了3本。
書名真的很重要！

Two million copies of the book *How To Change Your Wife In 30 Days* were sold within a week. Until the author realized that the book title had a spelling mistake. The book title was corrected to "How To Change Your LIFE In 30 Days". Only 10 books were sold after the change. This is a good evidence for the fact that to any man, his wife is always more attractive and more important than his life.
