For Latter-day Saints, there's a lot to "guard against" these days pride, pornography, debt, obesity. And since I'm always willing to give advice, let me add one more thing.
We need to guard against mistaking things that "stimulate" us for things that "invigorate" us.
So many films, concerts and spectacles create a sensory overload. We leave them feeling drained. We're like washcloths wrung out and hung up to dry. And we think that's a good thing.
