Humans tend to be like eggs sometimes. Hard on the outside, yet, like an egg, so thin that hardness is. Just superficially, skin deep, indeed, literally. While on the inside, lays the soft matter, which is the real one. Real egg, real human.
The soft one, protected by hard shell. Without it, that soft substance simply spilled out, making no good use. But after some treatment with heat, it'll make a beneficial product. Egg being incubated by the mother hen, for example, will God permits allow a chick to come out. Egg being boiled or fried etc, will make a nutritious food (Don't eat too much of them though).
So, don't be affraid to tempered, forged, by "heat" in this life. Like a german said, "What doesn't kill you will make you stronger".
Keep fighting the good fight, dear readers.
