Donald Winnicott was one of the most remarkable psychoanalytic authors of the last century. One of his most cited articles is "The capacity to Be alone" from 1958. In it he states that this ability is one of the most important signs of psychic maturity and that its gradual acquisition depends on having been able to establish, first, a bipersonal relationship with his mother -or with whoever exercises that role- in such a way that he has been building a non-threatening relationship with himself, where he can contemplate himself in harmony and without the need to react. In this interplay of self-observation, the ego, which is the conscious instance that observes the unfolding of the self, emerges step by step. It raises the concept of "orgasm of the ego", understanding it as a pleasant state but without sexual excitement or the need for physical discharge When you are alone with yourself, which does not necessarily mean being physically alone, you can express those particularities that will build an adult personality and in harmony with yourself.
