Natural Pessimists

Observing life, I have found humans to be naturally pessimistic. Even when they verbally express any optimism, there is that pessimistic darkness that looms inside.
When good news is received, there is that doubt. When something is going the right way, there is FEAR it may not go that way much longer.
My theory has continued to prove me right with the upcoming date of Dec 21, 2012.
There are numerous "beliefs" circulating; the most popular: the world will end at that time due to the planetary alignments which will change the Earth's magnetic field and cause natural disasters....have you seen the movie 2012? Other theories discuss the return of Christ (may not be on that date exactly) or the end of a great empire which many interpret as the fall of China or the U.S.A as a super power in the economic sense. Fact is, all of these theories have a pessimistic undertone. I have only learned of a couple of positive theories from people who are actually studying astronomy, geographical, meteorological and geological changes or who are relying on their spiritual connection with the universe to guide their emotional attachment to the date in 2012 (which in their studies, Dec. 21, 2012 does not play a significant role).
Regardless of what theories bombard us every day or what we chose to watch and believe, why do most decide to believe in the pessimistic view? Why would Hollywood put movies out which show NY city being destroyed by huge tsunamis and continue to make movies about "the end of world"? Why do humans DOUBT themselves and each other before believing?
For myself, I have chosen to allow positive energy to guide my life. I refuse to watch films depicting the end of the world, I catch that fear and pessimism inside of me and hold it in its own cage fighting to keep it there and I look to human beings as a way to understand myself.
We have been taught to be pessimistic. Pessimism=fear and fear=order...something the media, government and religion have mastered to create. Now it is time to have a brighter outlook, believe in yourself and BELIEVE in that faint light in your soul that provides peace when you allow.
