What are the benefits of learning the Book of Changes?

The Book of Changes can be described as "the first wonderful book in the world". It is called "the first" because the Book of Changes is the general source of China culture and the beginning of a hundred schools of thought, and is known as "the head of the group classics and the source of the avenue". Confucius said: I am determined to learn at five out of ten, stand at thirty, be puzzled at forty, know my destiny at fifty, listen at sixty, and act at seventy without overstepping the bounds. In Confucianism, "destiny" is the "objective law" derived from the Book of Changes. Confucius repeatedly studied the Book of Changes in his later years, and Wei compiled three poems. "Add me a few years old and learn the Book of Changes at the age of 50. It's no big deal." That means, let me live a few more years. If I learn Zhouyi at the age of 50, I can make no big mistakes. Why can I be "no bigger" after learning? In fact, just because we act according to objective laws, we naturally won't make big mistakes.
