We all have a past. In this past, we lived moments of sorrow, we experienced pain and sadness, we faced verbal attacks, insults, and humiliations. We have soul wounds… We cannot change our past. However, what we can do is transform the bad past into a valuable life experience that will be useful to us now, in the present. In this book, I want us to take a journey into your past together. To go back in time together, and through practical exercises and simple processes, show you how to heal your past. Every person's past is a co-construction, as there were other people who participated in it, influenced you, and intervened in your life. But you build the future. The emotional wounds you have will help you find the right path. There you will be able to turn your painful memories into a gift, so that you can help not only yourself but also others. The criticisms you received will turn into inner fulfillment, the traumatic memories into freedom, the sad memories into opportunities for growth and development, the jealousy and envy you experienced into self-esteem, the bad childhood memories into a successful future, the mistakes and failures into knowledge and progress and evolution… So when you remember the worst day of your life, you will perceive it as the best thing that has happened to you.
