There are men who struggle for a day and they are good. There are men who struggle for a year and they are better. There are men who struggle many years, and they are better still. But there are those who struggle all their lives: These are the indispensable ones.
Bertolt BrechtFor time flows on, and if it did not, it would be a bad prospect for those who do not sit at golden tables. Methods become exhausted; stimuli no longer work. New problems appear and demand new methods. Reality changes; in order to represent it, modes of representation must also change. Nothing comes from nothing; the new comes from the old, but that is why it is new.
Bertolt Brecht
