Before convincing oneself that travel guides are a stable component of travel inspiration, one must see the risk that the desire extinguishes even before opening a book.
The threshold to move from fiction to guide is high, and many aspirations never reach this point.
Many students are inspired by a film about ancient Egypt, but without a concrete mandate (a school trip, a highly motivated family), the idea remains just a film.
The drawdown of interest is rapid when faced with time or budget constraints, making the guide a superfluous expense.
The role of the guide is conditional; it does not guarantee the sustainability of the initial interest.
