Optimism and Pessimism

The optimism and pessimism are psychological terms and that is how psychologists distinguish people according to their perception of this world. There are optimists who always see the bright side of the moon and there are pessimists who always see the dark side of the moon. Those people together may be recognized as a harmony of this life.
Though, it is better for people to be able to combine those points of view in the – this is the best choice one can ever make. There is no way for those to extremes to live on their own without a polarity that would bring them to balance. Optimists never think about the dark side and so they are not ready for something wrong happen to them.
But, the pessimists are polarities for optimists and they see the dark side only and they never see the bright side. In case they will see the dark side only they can go mad. It is impossible for a person to live with negative thoughts only. That is why pessimists need optimists who can show them that there is the bright side. And that is why optimists need pessimists who can show them that there is something they have to be prepared for.
Optimism and pessimism together make a happy medium that is the harmony, and the harmony, as you know, is the same with happiness. Happy people always see the real world and they are ready for everything and they know that they can handle with everything they have to handle.
