One of the knowledge that has been confirmed by research is related to the capacity of neurons to functionally adapt and thus diminish the effects of structural and functional lesions in the brain, commonly called brain plasticity. Cognitive reserve is also mentioned, linked to the ability of people to minimize the decline that is naturally generated in the brain as a result of age or any pathology, even managing to delay or reduce the presence of clinical symptoms in the person. Having these discoveries in mind, the next step is to structure the strategies and mechanisms that will allow us, day by day, to positively influence the situations that we face in our daily life. This is what Dr. Miren does in this book. She uses metaphor to invite us to build and use the Magic Box of Psychological Resources, inside which we will find our most precious jewels; the mechanisms and strategies that will allow us to maintain our personal wellbeing at a high level.Guillermo E Arias M.Ph.D. in Psychology
