Joseph F. Smith, Journal of Discourses — Volume 25…
“ Jesus said, "When ye fast, be not, as the hypocrites, of a sad countenance. * * But appear not unto men to fast, but unto thy Father which is in secret. In other words, appear to the world to be happy. This is the privilege of every Latter-day Saint, and indeed the privilege of every soul that lives. There is abundance of joy to be obtained aside from the joy which ends in suffering and sorrow. Seek those joys that bring no alloy with them, those joys which are unremitting, eternal in their nature. ”
