"Only those live who do good."
                            Count Leo Tolstoy
                                   
What Count Leo Tolstoy says is that those who live are those who do good. This is a really good quote because those who do good know how to live happy lives. In the other hand we have those who don't do good they chose to be unhappy and bad. this also means that those who don't do good don't deserve to live compared to those who do good they should.
