"Only those live who do good."-Count Leo Tolstoy 

What this quote means to me is that only people who do good in their lives are really living life. Those who choose to do bad things never prosper or do anything worth meaning in life. In order to fully live life you need to be able to do the right thing. Doing good is better in life than doing the wrong thing. Those who choose to do the wrong thing never get anywhere in life and always struggle. On the other hand those who choose the right thing always get ahead in life and never seem to struggle. They are more optimistic. Those who choose the wrong are always pessimistic. In order to live life happy one must do the right thing all the time. That's the way to get the best experience out of life itself.
