Who could refrain that had a heart to love and in that heart... - William Shakespeare

"A lover goes toward his beloved as enthusiastically as a schoolboy leaving his books, but when he leaves his girlfriend, he feels as miserable as the schoolboy on his way to school. (Act 2, scene 2)"

"Tongues in trees, books in running brooks, sermons in stones, and good in everything."

"And this, our life, exempt from public haunt, finds tongues in trees, books in the running brooks, sermons in stones, and good in everything."

"If music be the food of love, play on."

"There's no art to find the mind's construction in the face."
