Paradox quotes help!?

Does anyone know a good quote that's a paradox? maybe from a movie, or tv show, or song or something? ive literally been looking everywhere and i cant find anything really great. I have to be able to write about some of the the things i thought of when i was yzing it. ive found one that i might be able to use, its "I have found the paradox, that if you love until it hurts, there can be no more hurt, only more love." -Mother Teresa. Im not sure about it though. I don't know if i can write a lot about it. but, anything helps! thanks!
