One lesson is patience. Just as a long story unfolds gradually, so does life. We need to be patient with ourselves and the process. Things may not happen overnight, but with time, we can achieve great things.
The fact that life is a long story teaches us about the value of growth. Over time, we should strive to become better versions of ourselves. We learn from our experiences, both good and bad, and use that knowledge to grow emotionally, intellectually, and spiritually. Each chapter of our life gives us an opportunity for growth.
