I'm always coming but never arrive. What am I?

The elusive concept of a day that is perpetually on its way but never quite reaches the present moment perfectly describes the nature of "tomorrow." Each new dawn brings what was once "tomorrow" into the realm of "today," rendering the future "tomorrow" a different, still-unrealized point in time. It's a continuous cycle, where the future day we anticipate is always just beyond our grasp, forever remaining a day ahead, a promise that renews itself with every passing moment.

This riddle plays on our understanding of time as a linear progression, yet also a fluid and ever-shifting concept. We plan for tomorrow, we look forward to it, and yet, when it arrives, it has transformed into the present. This ongoing transformation highlights the continuous flow of time, where the future is constantly becoming the present, and the present quickly slips into the past. It's a fundamental aspect of how we experience the temporal dimension, always moving forward without ever truly "arriving" at a fixed future point.

Philosophers and poets alike have long pondered this characteristic of time, recognizing its relentless march and our inability to stop or hold onto any single moment. The idea that tomorrow is always coming but never truly here emphasizes the ephemeral nature of the present and the constant renewal of the future. It serves as a subtle reminder to appreciate the now, as what we call "tomorrow" will always be just out of reach, a perpetual horizon in the landscape of time.
