What does eight-character confusion mean?

People in their thirties have never achieved anything, but they have been sleepy or confused before. It is very dangerous to change your destiny by your own mentality. You live passively all day. I suggest you read the Book of Changes, which was written by Confucius and his disciples. The first hanging is: work for the sky, strengthen the sky and strive for self-improvement, which means that the sky is vigorous and powerful, and people should strive for self-improvement like the sky. I hope you are full of confidence and face strangers with a positive attitude. The ancients said: Heaven rewards diligence, where can you get a reward without paying? You can't change your destiny with eight characters. I wish you better and better.
