You can’t win unless you learn how to lose.

The line frames losing not as the opposite of success but as a prerequisite for it. “Learning how to lose” implies developing resilience, humility, and the ability to extract lessons from defeat—skills that prevent setbacks from becoming identity or paralysis. In a competitive context (sports, work, art), it also points to emotional discipline: accepting outcomes you can’t change, respecting opponents, and returning to practice with clearer priorities. The quote’s deeper claim is that winning is a process of adaptation; without the feedback and character-testing that losses provide, improvement stalls and victories become fragile or accidental.
