"Only those live who do good".
This quote means that people that do good in life get good things in return. Like if you work you are going to be proud of that because you earn that money the right way. You worked for it your self. Also because if you steal in your job they might caught you. You are going well to jail. Thats when you probably start to think if what you did was right or was wrong. You think why you did that , that if you done a different choose you would not be in there. But now you have to be there for many years now.  If you do bad. Bad will always come back to you some how. In the other hand if you do good good things will come to you.  Good is always going to make you feel good. Every thing you do with good people are going to thank you and you always going to feel good about yourself. If you do wrong then every you doing is wrong but it your choose if you do good or bad.
