Rozbroić narcyza. Jak radzić sobie z osobą zapatrzoną w siebie

The book offers actionable advice, but I'm curious what personal experiences or research led to these particular approaches.

The description is in Arabic and seems to include cultural nuances—how did that influence the advice given for managing narcissism?

I'm wondering if the methods are adaptable to different types of relationships or personalities, or if they work best in specific contexts.
