It is the creation that follows the emotions. The perfection in form is required to intrigue human mind and soul. But it’s not only the visible part, mostly it is the invisible one.
A great carpenter isn’t going to use bad woods for the back of the cabinet, even though nobody is going to see it.
So targeting the perfection is how we advance ourselves and the future generation. And it means caring about the craftsmanship even of the parts unseen.
