If you don't wan't to be a sheep, then do the following:
Write to the political leaders that affect you, or others that you care about. Tell them what you like. Tell them what you don't like. Tell them ideas you have on how to resolve issues or correct problems. Be polite and respectful.
If you win the lottory, do the same, and make campaign contributions. Remember, in the end, leadership's only real motivations right now are cash and more cash. Get a financial and legal advisor to help you in making sure you don't do something that could get your cash and freedoms taken away from you.
Convince your friends to do the same thing.
Elections are popularity contests. Become popular enough to become elected to some position. Make sure you are extremely well known. The more well known you are, the better position you can enter. In each position, quietly but firmly try to do the right thing for those who are unprotected by freedom. The right thing is what THEY consider is right, not what YOU consider is right.
Gain a small army and start an insurrection (more likely to be killed in the process - highly recommend against this).
