Khalil Gibran expressed it like this: "You can avoid crying all your tears, but you won't laugh all you laughter then." Highly recommend reading The Prophet by him. A thin book, saying a lot with a few words.
(edit) Another favourite quote of mine is from the chapter about pain: "Your pain is the breaking of the shell that encloses your understanding."
