Life's Dynamics:

Life is very clear and logical, it is people who make things complicated by their lack of objectivity, it is difficult for people to see things and most important accept things for what they are.

Most people round the edges ( I mean,  ‘most people make things look better than they are) and adjust the color to be rosier in order to make situations fit their inner desires. When such things take place,  no warnings from people around can help because people truly believe they can change the circumstances to fit their vision.

In literature there is a term called indicating hint. It is a very simple but authentic  method to view a story and I think life as well. 

Throughout the story you view each character by the words they use and the actions they take, it is very accurate for you can easily know in the beginning of the story what to expect from each character for there is a clear pattern repeating it self.

In life it is the same, a person that failed you once most likely will fail you again (unless he went threw a radical change in his personality-I do believe everyone can change, but self work is required).

Believing that things will be different than they usually are is similar to  hoping that an apple with a small trace of decay will turn good.  There is no such thing, most likely the decay in the apple will get larger as time goes by and not the other way around and an objective person would know that.
