If you want to change the world, start with yourself.

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

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

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.

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

I'm one of those people that think Thomas Edison and the light bulb changed the world more than Karl Marx ever did.
