defining moment

Life-altering turning point

A defining moment is an event or decision that establishes or reveals someone's essential character, or that decisively shapes future outcomes.

The phrase suggests a turning point—before and after which things are fundamentally different: Her refusal to back down became the defining moment of her career.

Often used retrospectively to identify when something crucial shifted.
