Rectangle of life?

Recently I came across a book named "Are you ready to succeed". While the title is clearly cheesy, initial premise of the book looked interesting, so I went and found an extract of the book for a quick read. Am yet to read the full book, however, the initial premises on which the author expands seemed quite fascinating to me and I thought I should expand on these before they left my mind. 

Based on this limited reading, I picked up four key ideas in the book (interestingly, one of which I have been aware of before) and to me it seems like these form the four points of a quadrilateral within which life revolves. The four points/pillars are a) mental models  b) multiple realities c) mental chatter and d) witness

The central theme is (mind you, I have not read the book, hence am just connecting the dots based on my hunches) - life is a sequence of events. Imagine yourself as an unattached vacillating sub-atom, sitting on a string connecting a node called "mental models" and other node called "set of possible realities". The sub atom is the “witness” and is surrounded by a cloud called "mental chatter". 

Now, as events happen in the "realities" node, the sub-atom watches the outcome and takes a model from the "mental models" node and applies it to the event, which supplies “one possible interpretation” of the event and connects it to earlier events in our life and evokes emotions/responses in the sub-atom. In the process, the interpretation and the responses are sent back to the model node where the models are updated for future applications. 

So far, this seems like a logical automaton and can remains so as long as the sub-atom is simply acting as a witness to the events happening, using models to search for interpretation, but consciously knowing that models are "one way" to explain an event, but have their limitations and hence don’t offer “absolute truth”. 

More often than not though, the sub-atom is surrounded by a cloud called "mental chatter", which constantly throws its own interpretations to the events happening, sometimes questioning the mental model's capability, sometimes strongly emphasizing that the interpretation of the model is the whole truth and only truth.

How many times have we heard people say - "why me, why did this happen to me?" Or, that "I am unlucky". Or that "things don't work out for me ever". Well, they just witnessed an event, applied a mental model without knowing its limitations which told them that they always get shortchanged unfairly. An objective assessment would be "well, this event happened and based on my previous life, my mind is interpreting it in this way". The watching person can step aside, watch him/herself, interpreting that event and get amused, of course all of this is infinitely easier said than done. But imagine if you tried living this way, wouldn't life be infinitely simpler?  Imagine the bliss when at every point, you remember that your life is confined within a rectangle made of these four points. You can then elevate to such levels where you interpret events as just events, like watching a dance on the sidewalk, without any emotional implications, and then quickly move on the next event and the one thereafter. If one can do it, this will be a true acceptance of our infinitesimally small existence in the billions of years old cosmos. Question then, is really this - can you remember to see yourself as a mere atom all the time?
