No gold is pure and no one is perfect. No one is a saint, and no one can do anything wrong.
Since ancient times, people have experienced joys and sorrows, and the moon has waxed and waned. Many things have already happened, why do you have to worry about it anymore?
No one or anything in the world can achieve perfection, so you don’t have to set such ridiculous standards of perfection, you just have to do your best. Just try your best to do everything well.
