Shakespeare

I have not read much Shakespeare but I shall share the lines that I particularly like; for I cannot pick just one.

"A fool thinks himself to be wise, but a wise man knows himself to be a fool."

"Be not afraid of greatness: some are born great, some achieve greatness, and some have greatness thrust upon them."

"Hell is empty and all the devils are here."

"To be or not to be..."

"I would challenge you to battle of wits, but I see you are unarmed."

Those are just some of the ones that I like, but there are so so so so many others.
