With what sharp checks I in myself am shent,  
When into Reason's audit I do go:  
And by just counts myself a bankrupt know  
Of all the goods, which heav'n to me hath lent:  
 
Unable quite to pay even Nature's rent,  
Which unto it by birthright I do owe:  
And, which is worse, no good excuse can show,  
But that my wealth I have most idly spend.  
 
My youth doth waste, my knowledge brings forth toys,  
My wit doth strive those passions to defend,  
Which for reward spoil it with vain annoys.  
 
I see my course to lose myself doth bend:  
I see and yet no greater sorrow take,  
Than that I lose no more for Stella's sake.
Sir Philip Sidney
