1. Repetition. If you repeat something enough, and with enough emotion and empty rhetoric, people will believe virtually anything.
2. Get the brainwashee while they are young and control their education. If you are the only one teaching them, you can control what they believe.
3. No reading. Teaching the brainwashee to read will only encourage him or her to start looking into new information. New information that may contradict what you want them to believe.
4. Let them believe they have power. Pick a weak one of them that you can easily control and manipulate. Puppets are the easiest way to gain trust.
5. Distraction is a key word here. Get their minds off the issues and onto entertainment. If they persist in politics or ruling or laws, set up an unimportant issue and let them debate about that while you keep deciding the real laws.
6. Tell stories about other people being brainwashed. That will make them think that they are aware of the idea and since they are aware of it, it can't happen to them. If they do start asking, though, cease immediately and distract.
7. Appeal to emotion by entertainment. Music is a huge deal here. Virtually every emotion can be controlled by a few notes.
8. YOU are the puppet master. Only YOU. Learn that now. There can only be one person pulling the strings.
9. Any signs of rebellion must be eliminated immediately. First by beatings, and only if the rebellion continues by execution. NO banishment. Banishment will only allow word of the brainwashing to leak out into the general public and that may pose a problem.
10. Have no sympathy. Sympathy will make squashing a rebellion very difficult.
