"完璧主義は自己破壊的です。それは完璧というものが存在しないからです。完璧は達成不可能な目標です。"

Simplified Meaning:

Trying to be perfect can be harmful because nothing in life can ever be completely perfect. This means that chasing perfection is like chasing something that doesn’t exist. Imagine a student always aiming to get 100% on every test. Even if they get 99%, they feel like they failed. This constant pressure can make them stressed and unhappy. Instead of this, it's better to aim to do your best and accept that sometimes things won't be flawless. If you do your best and learn from your mistakes, you can still succeed without the pain of always seeking perfection. For example, an artist can spend forever trying to make every detail perfect and never finish their painting. But if they accept that imperfections are human, they can create beautiful and meaningful art and feel satisfied. In daily life, focusing on doing well rather than perfectly can lead to more peace and happiness.
