About this quote
Widely attributed to Muhammad Ali from interviews, though no specific dated source has been verified. The metaphor is characteristic of Ali's aphoristic style — grounding a psychological insight about endurance in an instantly recognizable physical image. He gave hundreds of interviews throughout his career and was known for producing quotable lines spontaneously in conversation rather than from prepared text.
