Feelings of love and gratitude arise directly and spontaneously in the baby in response to the love and care of his mother.
My psycho-analytic work has convinced me that when in the baby's mind the conflicts between love and hate arise, and the fears of losing the loved one become active, a very important step is made in development.
The highly ambitious person, in spite of all his successes, always remains dissatisfied, in the same way as a greedy baby is never satisfied.
