"Breakthrough Power: Psychology for Effortlessly Surpassing Your Limits" Mentalist DaiGo Price: ¥1426 #MentalistDaiGo #Book #Society/General I bought this new and read it once, then stored it at home. The writing is easy to understand, and the book is structured in a way that keeps you engaged, with illustrations and practical exercises. I thought it was a very well-written and thoughtfully designed book.
