What is the understanding of "looking up at the stars and keeping your feet on the ground"?

Only by looking up at the stars can we find the right direction.

Looking up at the starry sky, we can see the vastness of space, the wonderful beauty of the splendid starry sky and the magical picture of the starry arch. How beautiful the night sky is, it is a wonderful feeling beyond words, which inspires people's yearning for the unknown world and a better life. However, for this beautiful scenery, many people really just bury themselves on the road and miss this strange feeling, and even get lost in the dark and get stuck in the mud.

On the contrary, if we can always look up at the night sky, our minds will be broadened and our direction will be more clear. Nothing between heaven and earth is broader than the boundless blue sky. What is broader than the blue sky is people's thoughts. Only by keeping our feet on the ground can we reach the other side of the ideal. The ideal is undoubtedly beautiful, but the road to the ideal is rugged and long, just like the glorious laurel is always woven with thorns. If a person can't keep his feet on the ground, one step at a time, his ideal will eventually become a bubble. Only from here and now can our cause leave a clear track.

Looking up at the stars and down-to-earth are not isolated, but complement each other. Only when you are ambitious can you find a career to fight for all your life; Only by keeping our feet on the ground can we get closer to the ideal step by step.
