The cherry effect or the issue behind well-being.

Humans define well-being on predefined assumptions, based on inner and outer criteria as references. As illustrated, these criteria are subject to constant change, even in a situation when one is acting freely and is in control of all possible external influences. Even in scenarios that seemingly allow autonomy with one variable to analyse, underlying "irrationality" affects our ability to define and operationalize any desirable trait or state, such as well-being, euthymia or health. Before eating a bowl full of cherries, one creates an idea of how much cherries he/she will eat. However, as one starts eating, perception and following assumptions change. As cherries labeled as most desirable disappear, other cherries start to appear more alluring. The cherry effect could be of relevance in defining the terms such as well-being, euthymia and basically any other term encompassing a complex category of the human condition dependent on our perceived reality.
