A sentence starts out like...

     A sentence starts out like an overly confident explorer wandering the jungles of the wild. With a big bag on his back, like the weight on a writer's shoulder to make his or her piece good. Sword in hand chopping down any trees or bushes in the way, like a writer having to tear down common beliefs in order to make way for his or her own thoughts to be put into the wild and to possibly be torn apart by a few lions, or critics. There's a sense of fright that develops in the sense that the writer, or explorer,  is entering uncharted territory and knows this... but still proceeds to do so anyways.
