A hard, strong substance like a diamond, a concrete wall, even a tooth, can withstand the test of pressure and beatings.
Sometimes though, the pressure can be too much. A sharp and/or pointed object can weaken and fracture any tough thing.
That’s why a lot of times, being strong isn’t all it’s cracked up to be.
You can make any thing stronger by coating it with protection, creating a better foundation, or studying and rebuilding it.
But it needs to be broken to be rebuilt.
And not everything needs to be rebuilt.
