I agree tremendously with Marcus. He states that we should only worry about what we have complete control over, which is not much. His philosophy is quite similar to the ways of Buddhism in the idea that one must not fret about the minutia in life, but instead, enjoy it for all that it is. When one can fully be at peace with the uncontrollable, they will continue to see success in everything they attempt. It is a better way to go through life. There is no point in becoming concerned with the inevitable. I believe the quote's main goal is to exemplify the fact that you can not trust anyone or anything. Overall, the world is not a safe place; one must never believe fully what they are told, or how they view the world. It is all a matter of perspective when we break down the bare essentials of life. Therefore, there can never be a "complete" truth in anything that takes place in the world. In conclusion, Marcus hits the nail on the head with his quote. It exudes the real meaning of the Buddhist idea of slavation and Enlightenment.
