Shakespeare

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 I am kinged again, and by and by
Think that I am unkinged by Bullingbrooke, and straight am nothing.
But what e'er I be, nor I, nor any man that but man is
With nothing shall be pleased, till he be eased with being nothing.

Shakespeare, Richard II Act 5 Scene 5
