To render strings of scenes from your head into words on paper that another person could read in order to recreate the voice of someone unmet, and at the same time be presented beautifully and clearly; to choose the right words making the right phrases making the right sentences making the right paragraphs making the right chapters, and to have these chapters interweave into a cohesive story that manages to fulfil the reader and make him feel joy, sorrow, despair, or hope; is insanely meticulous, and inanely ridiculous.
And to come up with characters that need to feel alive: to have to be so many people at once, each with their own dreams, wants, thoughts, feelings, identities, and treasured memories, how can one not explode? How can a mind not erode?
And of all the hobbies, passions or pastimes a human being can engage inβ from juggling chainsaws on a tightrope to playing the piano while painting yourself playing the piano to sculpting a hypercubic klein bottle, nothing is as delicately difficult as juggling a thousand possibilities of plot on a swinging tightrope of self-doubt while playing the instrument of your vocabulary to paint a scene revealing itself magically all the while sculpting an entire universe(!) piece by piece from the flesh and bone of your own pregnant imagination.
Who, then, but only the most idiotic, brave, ambitious, and diabolic self-haters and self-lovers would write a book? It's a noble task, to be sure, for without its fair dose of literature, mankind would crumble and un-create back to the unthinking, unfeeling dirt from which it is made.
