What does Be the change you wish to see in the world mean?

These Words, first said by Ghandi, basically mean that you have to be the first person to implement changes that you want to see in the world. In other Words, if you see something in the world that you don't like (such as violence), you must change yourself to be non-violent in order to set an example, not be a hypocrite, and to provide impetus for a shift towards non-violence.
