If people can put that much intent into one day, as we do every year on Nov 4, then we can do it everyday. And if enough people do it everyday - or even try to do it everyday - the world will start to change. It will start to change because that is the only way it is going to change.
Who would want to ever let that go?
It really doesn't matter if you believe that peace blogging is a small thing or whether it has the ability to alter the way we live and the way countries interact. You may believe that your splash in this pond means nothing more than a quickly dying ripple. That belief would be wrong. Because in the meta world of algorithms and synchronization, we are way past the point of needing to measure the effect of our words. Whatever they are, they have great power. So choose them wisely. Start to think now what you will say to the world in November, because those words will never go away.
What you do and say as a peace blogger is indeed immeasurable.
