Last night I happened to talk a little about politics. Not political ideologies, parties and such, but about the real politics, how to do something to change the society where you are living in. There was a friend of mine who does not believe she can make any difference in the world, which is a very common feeling at least here in Italy, and a guy she met last night whom I could depict as a "Berlusconian communist": he really is the kind of communist Berlusconi is so afraid of, one of those with a long beard who believes in revolution and such. Now I usually don't like much that kind of thinking, but he made some good points and I was glad to talk to someone who had an understanding of a real democratic process, even though we would never agree on a lot of things. Anyway my friend was basically asking where do we find the courage and inspiration to go on and fight for something different, how do we know that what we do makes any difference? Since I think this is an important question, I will write here my answer to that.
