I don't think being tidy is always necessary. Some people are actually more creative in a slightly messy environment, and as long as it doesn't affect their work, I think it's fine. Everyone has their own way of living, so it's really a personal choice.
私は整理整頓が常に必要だとは思いません。実際、少し散らかった環境の方が創造的になれる人もいて、それが仕事に影響しなければ問題ないと思います。人それぞれ生活の仕方があるので、本当に個人の選択だと思います。
