Doubt thou the stars are fire, Doubt that the sun doth move.... - William Shakespeare

"Who could refrain that had a heart to love and in that heart courage to make love known?"

"The course of true love never did run smooth."

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

"There's a tide in the affairs of men, which taken at the flood, leads onto fortune, omitted, all their voyages end in shallows and miseries. Upon such tide are we now..."

"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)"
