Kintsugi is the Japanese art of filling cracks in ceramic with gold. Instead of throwing a piece of pottery away when it becomes damaged, the cracks are filled with something new. The pot becomes unique; its damage becomes a part of its history. It makes it truly one of a kind, often even more beautiful than the original version. And because it's mendable, it may long outlive other forms of pottery.
I think people are a lot like this pottery. We get broken, or a little cracked. But we hold on and keep growing, and try to become better. Our weak spots can eventually become beautiful as we learn to either overcome them or to live with them. Both options take strength and courage to implement; fighting our demons or learning to coexist with them is not easy. The resulting marks are shining scars of the many battles we've survived.
A wound that has healed will likely always bear a scar, but scars are nothing to be ashamed of. Why? Because dead people don't get scars, because the wound fucking killed them! So that scar means you survived that shit, you badass motherfucker!! And that's impressive, even if it was by the skin of your teeth. ;)
