Change

Change is one of the most disruptive agents there is. It dismisses the old, the proven, the established and it unsettles the way things currently are. It brings about uncertainty and forces people to question what they once believed to be true. Change comes to every industry, every society, every government, and every person, and creates a number of enemies along the way. But while most people hate change one might agree that without it there is no progression and no forward movement of industries, society, or mankind. 

So, be the change. But if you're going to be the change be equally prepared for the change towards you that comes with it.
