Why we have to vote?

I know that believe in politician is something like a superstition, that politician only want to use the citizens for their benefit, then they get apart of people and then trick them. That practices that we see every election takes away people  desire to vote. But we must not lose our willpower, why should we vote? We have to vote  because we have to fight for our city,  because we pay the consequence when the politician take a bad decision; we have to vote against them, we have to vote because good choice will always bring progress, superiority and we can improve our political science.

So, if our form of government is bad we cannot stop  voting cold turkey, because that way we let them destroy the country.
