The marriage of true minds

I've often asked myself what, exactly, it was about Shakespeare that made me fall in love (and yes, the emotions were very similar) with him and his plays when I was a young teenager.  I don't know.  Maybe it was too long ago.  Maybe there is no reason to it.  At any rate, when I discovered this poem in English class during my senior year in high school, I liked it so much I memorized it.  And I've never forgot it.

Sonnet 116

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 proved,
I never writ, nor no man ever loved.

(I typed that from memory, just so you know.)
