Remember that in every difficult situation, you have two choices: get better or get bitter.
Good propaganda does not need to lie, indeed it may not lie. It has no reason to fear the truth. It is a mistake to believe that people cannot take the truth. They can. It is only a matter of presenting the truth to people in a way that they will be able to understand. A propaganda that lies proves that it has a bad cause. It cannot be successful in the long run.
