"They're only truly great who are truly good" 

-George Chapman 

 This means that  there is no other way to be great, than by starting to be good. You must be a good to be a great person. You can start to be good in many ways such as by become good in your morality and I your ethics. For example choosing to do the right things in life like not doing drugs or drinking alcohol. This is almost an example of good karma if you do good you will be a great person in life.
