Untidy? NO, “Un Tidy”. 「散らかってる?違う、"散らかしてる"んです。」 片付けなんて、もうやめませんか? UnTidyは、片付け嫌いの救世主 - 「きちんと整理整頓」「決まった場所に収納」 もうそんな努力はいりません。 - 整理整頓が苦手でも大丈夫。 UnTidyは、「どこに入れたか」だけを記録しておけばOK。 こんな経験ありませんか? - 30分かけて探しても見つからない - 「ちゃんと片付けて」と言われる - 整理整頓本を買っても3日坊主 - 頑張って片付けたのに、翌日には元通り… Un Tidyなら、散らかったままでOK ぐちゃぐちゃに突っ込んだ引き出しも、 とりあえず置いた棚の奥も、 なんでも入ってる謎の箱も リビング > ソファ下 > 謎の箱 > 充電器 ↑ こんな雑な場所でも、ちゃんと見つかります。 全部そのままで、10秒で見つかります。 超簡単 3ステップ 1. 適当に放り込む 2. 「どこに放り込んだか」だけ記録 3. 探すときは検索するだけ もう「片付けられない自分」を責めるのはやめましょう。 大切なのは、「片付けること」ではなく、「見つけられること」。 それがUnTidyの考え方です。
