Self-learning is an exercise that we practice naturally from birth and never leave you develop throughout life. According to each case, this natural ability can go to refine in greater or lesser degree depending on the social and environmental factors in which each individual develops as well as of their cognitive abilities. In general the use of the term self-learning refers mostly to the acquisition of knowledge at academic level and is defined as a self-taught to anyone who managed to obtain knowledge on their own. Self-learning begins in many cases as a game, and as he passes time becomes aware that what has been learned is valuable and useful. The self-taught is usually from childhood and as the years go run, va (sometimes unconsciously) polishing or perfecting their techniques of study. In other words, learn to learn. And usually develops methods that produce satisfaction, who does not get bored, and that facilitate the absorption of knowledge. Despite that this modality of study might have detractors (who based his position on the idea that the self can never identify a true information from false), this form of learning often get better results than studies obtained in formal areas.
