Difficulties foster obsession. We constantly justify contradictory actions, both our own and others, often without recognizing our own inconsistencies. There's a saying in English, 'Easy come, easy go', suggesting that what is easily gained is just as easily lost. However, the opposite also makes sense: what is hard to acquire is hard to fade away. What is not easily won, does not easily leave. Staying, it consumes our time and becomes a habit, distracting us and blinding us to superior alternatives. This is evident in contradictory interpersonal relationships or in the insistence on remaining in adverse situations while searching for justifications. This paradox is known as cognitive dissonance, particularly affecting the stubborn, rigid, rule-following, and conservative individuals, and can be considered a 'disease of thought'. In summary, it could be diagnosed as 'knowledge dissonance'.
This obsession makes us vulnerable to external manipulators who exploit our weaknesses for their benefit.
