C.S. Lewis dismantles the common misconception that ambition has an expiration date. The phrase "never too old" is a powerful affirmation that time and age are not barriers to new beginnings, but rather platforms of experience from which to launch fresh endeavors.

The distinction between "set another goal" and "dream a new dream" is crucial. It acknowledges that our journey involves both the practical, actionable steps of goal-setting and the boundless, imaginative process of dreaming, both of which are perpetually available to us.

This quote serves as a timeless reminder that life is a continuous cycle of creation. It empowers us to constantly reinvent ourselves, set new goals, and nurture new dreams, regardless of our stage in life.
