Back to the forget-me-not metaphor.
"Second, forget not the difference between a good sacrifice and a foolish sacrifice."
It's easy to get caught up in worldly things, to sacrifice the good for things that have no eternal significance. I have done this, telling myself that finding success in my writing, or having a nicer home, or buying the latest fashion is more important than things of lasting value--faith, family, and friends. All I can say is that I'm trying to do better.
So, for today, I am grateful for those times when I can distinguish between a good sacrifice and a foolish one.
