※ Although 8 books are shown in the photos, I am selling 4 of them at the listed price. Please choose 4 books after purchase. I bought and read these books at a bookstore when I was struggling with work. After reading them, I stored them in a dark place. Each book originally cost around 1000 to 1600 yen. There are a few folds as shown in the photos, and some dents on the covers, but overall, they look good. Please refrain from purchasing if you are looking for a perfect item, as they have been stored by a private individual. I will package them with waterproof protection and ship them via Yu-Packet Post. ・I am me, and idiots are idiots. ・Starting with "Doubt" ・Adlerian Work Techniques for "Stress-Free People" ・Joy at Work ・The Way of Thinking of People Who "Don't Overthink" Derived from Cutting-Edge Research ・The "Sensitive Person" Book ・How Sensitive People Can Work Without Breaking Down ・The Complete Guide to Eliminating "Toughness" at the Workplace Thank you for viewing. When you're feeling down, reading books to find solutions is a good idea, but going to the hospital is the best option if something happens.
