This is a mini-guide to critical thinking when reading business, popular science or pseudo-scientific literature. On every corner, in every advertisement, you are promised the rules of success, a step-by-step guide to a happy life, 8 main habits and much more. What are all these people talking about? This book is a challenge to your beliefs and attitude towards literature. This book is not the ultimate truth; let’s do without ultimatum statements. This book is a review of all literature at once.
