This is a bestseller that clearly summarizes the essence of Adlerian psychology in 100 short quotes and explanations. It condenses Adler's ideas, known from books like "The Courage to Be Disliked," in a way that can be applied to everyday worries and work. It's a book like a mental supplement, where you can find words that resonate with you no matter where you start reading. ● Condition The condition is relatively clean, as shown in the photos. I read it once and then stored it carefully. Thank you for looking.
