What does this quotation by mahatma gandhi convey about change?

you must be the change you wish to see in the world.

everything around the world is constantly changing, and we must also work on changing ourselves to fit better into society.
people are often able to see only one side of change because of their own feelings, desires, and ambitions.
people will change into better human beings only when the world as a whole has become a better place.
if we want the world to be a better place, then we should first work on making positive changes in our own lives.
