And I'll give you the million dollar answer (but you can keep your million, because I ain't gonna need it where I'm going).

Nothing, you don't have to give a shit about tyranny. Yes, I know, we all want to be that generation that changed everything, that fought against tyranny and won and lived a happy life and the future generations never forgot of how important we were. But we won't, cause in a thousand years from now, it won't matter. So stop giving that much importance to yourselves and live your lives.
