It’s hard to put into words what kind of euphoria a person can feel just by telling off what’s been getting to them. “So why not do it regularly?” asks the well-known German writer Alexandra Rheinwarth in the pages of her book. Quarrelsome colleagues, parents’ chats, office hangouts outside working hours, worries about waist size—all of it deserves to be told off seriously and for a long time. The main thing is to approach it wisely. Set priorities, weigh “pros” and “cons,” and skillfully get rid of the ballast in your life. Simple and with taste.
