Some people say that they can't be bothered voting because it won't make any difference to the outcome. Of course, I agree that it won't make any difference to the outcome. You might say, a ha, but if everyone thought that then no one would vote. Well, I don't think that is true. Think what follows - people only vote because they think it will make a difference to the outcome. And then, people will only vote for people who are likely to get in, in a way, to prove themselves right. I suggest that the myth that "your vote makes a difference" is therefore propagated by the main political parties in order to maintain the status quo. I say to you that the chance that your individual vote will make a difference is so unlikely that saying such things is ridiculous.
Instead of thinking of voting as a method of defining what the country is, think of it as a way of defining who you are. If you are old, you probably have defined yourself already. But, if you are young, there is a real opportunity to say something about yourself. I think that is more important than who runs the country anyway.
