Prince Hal's Monologue (The Hollow Crown, Henry IV pt.1)
I know you all, and will awhile uphold The unyok'd humour of your idleness. Yet herein will I imitate the Sun, Who doth permit the base contagious clouds To smother up his beauty from the world, That, when he please again to be himself, Being wanted, he may be more wonder'd at, By breaking through the foul and ugly mists Of vapours that did seem to strangle him. If all the year were playing holidays, To sport would be as tedious as to work; But, when they seldom come, they wish'd-for come, And nothing pleaseth but rare accidents. So when this loose behaviour I throw off, And pay the debt I never promised, By how much better than my word I am, By so much shall I falsify men's hopes; And, like bright metal on a sullen ground, My reformation, glitt'ring o'er my fault, Shall show more goodly and attract more eyes Than that which hath no foil to set it off. I'll so offend to make offense a skill, Redeeming time when men think least I will.
