as if one's life depended on it

Utterly without reservation

With maximum effort and urgency, as though failure would be fatal.

The phrase intensifies any verb describing exertion: She ran as if her life depended on it.

Often hyperbolic—the stakes are rarely actual survival, but the expression conveys total commitment: He studied for the exam as if his life depended on it.
