Positive psychology applied like any science speak only of the contributions of the research and conclusions falls short in practice and possibilities for people to be able to understand and seize the benefits that provide research, believe that we learn by doing and if we just stayed in fine words and encouraging theme, it will be forgotten, or remain as one knowledge in our head, we must shorten the gap between knowing something and doing something, so then I want to share the following exercise that has shown effectiveness in welfare and experimentation in having more contact with a happy life day to day. Positive exercise this year is easy to perform and does not require economic resources to do it, only your will and desire to know the benefits that these above mentioned scientists have described the positive psychology; you only need to have a book. In this book that will be personal begin to write starting today all the good that you remember that it has happened in the day (do it before bedtime), focusing on you in the positive emotions that you experienced and the actions and positive results in general, if you are married even better do it with your partner! As you’ll see the exercise it is simple and before rejecting it, let me tell you the scientific potential behind him. Currently the psycho-Neurology has demonstrated how our experience shaped brain circuits from which we tend to channel the new information, in psychology is mentioned with the name of mental schemes from which people have a vision of the world, to give you an example, in projective psychological tests that apply to patients and in where shows them a drawing, are asked to express a story aboutthey tend to do so from the brain circuits that have formed and thus an antisocial person could narrate aggressive stories, spite, hatred or discussion, instead under the same stimulus (drawing) another person could narrate a situation of personal improvement, effort and achievement; every one who has projected in the narrative part of your mindset and way of seeing the world.
