"Often people confuse hope with prognostics. Prognostics is the science of studying whatever happens around you in the world. With it either you will make a positive prognosis (because you are an optimist) or a negative prognosis (which would have a pessimistic impact on the people around you). But it is very important to differentiate. Hope is not prognosis. Hope is something that I see as the state of the spirit. If life had no sense, then there would be no hope, because the very sense of life, the meaning of life, is closely linked with hope."
