Let me not to the marriage of true minds (Sonnet 116)

William Shakespeare, 1564 - 1616

Let me not to the marriage of true minds   
Admit impediments. Love is not love   
Which alters when it alteration finds,   
Or bends with the remover to remove:   
O, no! it is an ever-fixed mark, 
That looks on tempests and is never shaken;   
It is the star to every wandering bark,   
Whose worth’s unknown, although his height be taken.   
Love ’s not Time’s fool, though rosy lips and cheeks   
Within his bending sickle’s compass come;
Love alters not with his brief hours and weeks,   
But bears it out even to the edge of doom.   
  If this be error, and upon me prov’d,   
  I never writ, nor no man ever lov’d.
