The world isn’t out there, Frank said with a wide gesture of his arm, the world as you see it has been invented by people not smarter than you. It is not something for you to see, nor a place to live in, but something you can change, mold, a playground for your ideas to meet other ideas. When you learn that you can change things, you want to change things to make them better, to make life better, to make life for others better. That is what is intended when people talk of changing the world, changing the world means repairing it, mending its holes, fixing what does not work and helping others do the same. After you the world will be different, changed, bettered. Now go.
