This is something Jospeh Smith said to his cousin George A. Smith when he had just walked 1,850 miles on foot serving a mission and was now suffering from inflammatory rheumatism:
"You should never get discouraged, whatever your difficulties may be. If you are sunk in the lowest pit in Nova Scotia and all the Rocky Mountains piled on top of you, you ought not to be discouraged but to hang on, exercise faith and keep up good courage, and you will come out on top of the heap."
It wouldn't seem so significant to me if it had come from someone who was just like, "chin up!" -- who had never had a trial in his life, but coming from someone who'd suffered a great deal more than I can imagine it sounds pretty good.
