To change the world you only need a pencil, a pencil is the only tool you need to teach the world to think, to see the world in a new light, to draw a masterpiece, to write a poem, a song or a book which awakens the world to a situation.
A pencil is all you need to create a masterpiece that allows others to do the same. Now some may say that pencil doesn’t last forever and this is true, but neither do we. A pencil is just the same as us, we have to leave our message before our time runs out. If the message you create with those few lines of granite lasts forever then that pencil has done its job and served the world and so have you.
