The Swedish version of this book was presented in 2007 with a new method to stop worrying that is the opposite of distracting and soothing techniques. The method aims at training the brain to decrease the production of discomforting, worrying and intrusive thoughts. Ph D Erik Andersson, Karolinska Institutet Stockhom has conducted two large scientific studies in 2017 and 2020. He found it most powerful.
In a personal email Erik Andersson wrote:
"Even better is that the results remain in the four month follow-up. What an incredible treatment model you have invented Olle."

The book has become very popular among people and is recommended by therapists, psychologists and doctors.
During the years readers have sent text messages and e-mails:

"I do not know how to thank you. Your book 'Quit Ruminating and Brooding' gave me a chance to a life. After postpartum depression, OCD and paralyzing anxiety, I had given up. I found your book and it saved me. Thank you."

"I bought your book about rumination and anxiety recently.I wish I had read it twenty years ago. It has given me understanding and tools to work with. Thank you."

"I have been feeling bad for a long time in my adult life. The fall 2016 was probably the worst ever. I could not manage my studies to become a lawyer and my relationship was suffering heavily. Basically, my whole existence was dominated by unrest. Your book introduced me to a new way to look at the thinking and quite soon I experienced enormous improvements."

"In the beginning of January, I read your book and much fell into place. Suddenly I understood that what my friends, my girlfriend, and my therapist had been doing for me was wrong."

"The psychologist Olle Wadström has written this fantastic book. He gives us a toolbox that can take us out of our anguish. The reason for your broodings may not be what you think, and the solution is vertiginous.
Read, learn, practice, and enjoy the tranquility that follows."
