The quote "On the heights, all paths are paved with daggers" from Robert Jordan's book "The Path of Daggers" suggests that achieving great success or reaching a high point in life comes with significant challenges and dangers. It implies that the pursuit of ambition often involves difficult choices and potential harm, emphasizing the harsh realities one must face when striving for greatness.

This notion reflects a common theme in many narratives where the journey to power or accomplishment is fraught with obstacles. The imagery of paths made of daggers illustrates the concept that even at high altitudes, where one might expect safety and triumph, one can encounter treacherous conditions that test their resilience and resolve.
