baptism of fire

The phrase "baptism of fire" is often used metaphorically to describe a challenging and difficult initiation or experience that tests one's abilities and resilience. It refers to a trial by fire, where an individual is forced to confront and overcome intense or potentially dangerous situations, often with little prior experience or preparation. It can be used in various contexts, such as describing a soldier's first experience in combat, an athlete's introduction to a highly competitive environment, or a newcomer's initiation into a demanding job or role.
