I read the book "21-day unthinkable challenge - a framework for creating real change" by Marcel Kuhn and was positively surprised. The book is very easy to read and written in clear, understandable language. You quickly get into the flow while reading and feel inspired right away to start your own challenge. The concept worked very well for me. I was motivated to consciously set aside time each day for my challenge. Of course, there were also moments when my motivation dropped a bit. During those phases, what helped me most was thinking about the progress I had already made, how far I had come up to that point. That gave me renewed willpower and perseverance. What I find especially exciting is that after the 21 days, something really did change. It feels as if my brain has been “reprogrammed” to some extent, because what was initially a challenge has now become part of my daily routine. I’m proud of that. I will definitely start my next challenge soon. My tip to anyone reading the book: try it yourself. It’s fascinating to experience how both body and mind respond to change and embrace movement, new experiences, and personal growth. A heartfelt thank you to Marcel Kuhn for being such a great inspiration in my life through this book.
