"There is such a thing as emotional rubbish; it is produced in the factories of the mind. It consists of pain that has long since passed and is no longer useful. It consists of precautions that were important in the past, but that serve no purpose in the present. The warrior has memories too, but he learns how to separate the useful from the unnecessary; he disposes of his emotional rubbish. A companion says: 'But that's part of my history. Why should I jettison feelings that marked my very existence?' The warrior smiles, but he does not try to feel things that he no longer feels. He is changing and he wants his feeling to keep pace with him." by P. Coelho
