'Thus play I in one person many people...'

And none contented: sometimes am I king;     Then treasons make me wish myself a beggar,     And so I am: then crushing penury     Persuades me I was better when a king;     Then am I king'd again: and by and by     Think that I am unking'd by Bolingbroke,     And straight am nothing: but whate'er I be,     Nor I nor any man that but man is     With nothing shall be pleased, till he be eased     With being nothing.   Richard 11 Act 5 Scene 5
