John Cena, the WWE champion and successful Hollywood actor, carries a broken pocket watch as a personal reminder to stay grounded amidst fame and success. During an appearance on *Jimmy Kimmel Live*, guest-hosted by Jeff Goldblum, Cena explained that he carries two watches: one that tells time and another that serves a deeper purpose. The broken pocket watch features engravings on both sides, each representing different emotional states he has encountered throughout his journey. One side bears the phrase 'comparison is the thief of joy,' which helps him combat self-doubt and reinforces his self-worth. The other side, inscribed with 'memento mori,' serves as a reminder of mortality, urging him to remain humble and recognize that success is a collective effort. Cena's practice of using this watch illustrates the importance of maintaining emotional balance, highlighting that the real challenge lies in protecting one's identity from the extremes of self-doubt and inflated ego.
