You have to begin to lose your memory, if only in bits and pieces, to realize that memory is what makes our lives. Life without memory is no life at all, just as an intelligence without the possibility of expression is not really an intelligence. Our memory is our coherence, our reason, our feeling, even our action. Without it, we are nothing.
When a good idea occurs, it has been prepared by a long time of reflection. But you have to be patient. We all have what I call the invisible worker inside ourselves; we don’t have to feed him or pay him, and he works even when we are sleeping. We must be aware of his presence, and from time to time stop thinking about what we are trying to do, stop being obsessed about answers, and just give him the room, the possibility, to do his work. He is tenacious, you see. He never loses hope.
