Lee is indebted to Guy for giving him hope to achieve his dream of becoming a ninja and guidance in realizing those dreams. However, Gai’s advice about hard work would do him no good in an operation that would restore his fighting ability, since his survival is a matter of luck, not skill or perseverance. Since his death would deprive him of his ability to be a ninja anyway, he cannot decide what to do. Guy tells him to go through with the operation, as Lee will only be even sadder if he gives up on his dream. If he at least tries to resume his life as a ninja, it will make a big difference, and he will definitely survive. Lee is still resisting, so Guy tells him that if Lee dies chasing his dreams, then Guy will also die for failing to pursue his own dreams and help Lee pursue his dreams. Thanks to Guy, Lee decides to undergo surgery.
