If you want to make the world a better place, take a look at yourself, and make a change.

Our greatest ability as humans is not to change the world; but to change ourselves.

No matter who you are, no matter what you did, no matter where you've come from, you can always change, become a better version of yourself.

As a man changes his own nature, so does the attitude of the world change towards him.

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

The philosophers have only interpreted the world, in various ways: the point, however, is to change it.
