The Protestant Reformation.
The Russian Revolution.
The French Revolution.
Be the change you wish to see in the world
In other words, if you want change, go do it yourself.
A matter of fact, I'm going to start working on changing the 9th grade reading list at my school. All the books are negative or tragic at the end (give or take one or two), and since my school has had two suicides...perhaps it's time to look at what was required of them.
Oh yea, and I buy into the theory that nothing happens without some great leader being born first. So get your act together and become great!
