Hamlet

 ‘'Not a whit. We defy augury. There's a special providence in the fall of a sparrow. If it be now, 'tis not to come. If it be not to come, it will be now. If it be not now, yet it will come—the readiness is all. Since no man of aught he leaves knows, what is 't to leave betimes? Let be.''

The definition of masterpiece. The exposure of the depth of human nature. The uncertainty that gnaws our souls and weakens our will. The despair. The injustice. The madness, real or not. The struggle. The regrets and the retribution. The readiness.

Hamlet. The greatest written work produced by humankind.
