"All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident."
Constantly challenge the status quo, the more you believe what the worlds believes to be true, the more likely you are to be subjugated.
Live a life of truth seeking, know that there is more of a motivation to lie to you then tell you the truth because people seek to control and the only point of controlling others through propaganda is to get something from them. Release yourself from the concept of knowing what is true and what is not, instead seek the truth with the understanding that most times you will not find it but you will get close and often that is enough to avoid being used.
