Change is from within and is demonstrated without.

Here is some humor:

A jelly fish in front of a mirror in the water.

And a frog swims up to the jelly fish and offers him a sandwhich

Which is really not likely

But lets entertain the possibility that sea creatures have changed

Now they suddenly like the taste of sandwiches

So they hang out together and chew.

That is a revolution

Now they go to the stream

And share their dreams

All around more dreams form

And more and more.
