I have reached the conclusion that I lack the power to change the world or any significant part of it. I only have the power to change myself. And the fascinating thing is that if I decide to change myself there is no police force in the world that can prevent me doing so. It is just my decision and if I want to do it, I can do it. Now, the point is that if I change myself, something may happen as a consequence that may lead to a change in the world.
