For a writer you have to be interested in different cultures, different backgrounds. You are not there to write only about your village. You're there to show a bit of your village, but also to understand other villages.
You can never solve a problem on the level on which it was created. Insanity: doing the same thing over and over again and expecting different results. A life lived for others is a life worthwhile.
When there is change, it must not alter the content of what propaganda is driving at, but in the end must always say the same thing. For instance, a slogan must be presented from different angles, but the end of all remarks must always and immutably be the slogan itself. Only in this way can the propaganda have a unified and complete effect.
