This is a practical, in-depth guide for those who are tired of being held hostage by their own memories—people who find themselves constantly living between “then” and “when,” while losing the only reality they have: the “now” moment. The book offers a clear, step-by-step system based on the principles of positive and cognitive-behavioral psychology, mindfulness, and modern philosophy. Its goal is to help the reader not just “forget the bad,” but to transform: turn the weight of the past into a resource for growth, and turn the pursuit of the future into the art of finding joy in the simple.
