C.S. Lewis (1898–1963) was a British writer, literary scholar, and Christian thinker, best known for The Chronicles of Narnia and works of religious argument. The saying “You are never too old to set another goal or to dream a new dream” is widely attributed to him, but its source is uncertain: no reliable connection to a particular book, letter, or speech is established. The longer version ending “for yourself and the world” also circulates, though it does not clarify the quote’s origin. It’s best treated as an unverified attribution rather than a confirmed Lewis quotation.
The thought is simple and reassuring: age need not close the door on ambition, imagination, or change. A new goal can be modest or bold, personal or aimed at helping others; what matters is the willingness to begin again. The phrase resonates because people often face transitions—a career change, a loss, a fresh responsibility—and wonder whether their chance to try something new has passed. Its invitation is not that every dream will come true, but that it is still worth making plans and finding meaning in what lies ahead. By adding “for yourself and the world,” the expanded wording gives that hope a generous reach: a new dream can renew your own life while also shaping what you offer to others.
