Literary editing of the book

A serious philosophical book about the meaning of life, about the relationships between people and human values. What to think about and what to think about:
“My friend, people have been complaining for centuries that they have a very difficult life, and that’s not surprising. After all, we were here to pass the lessons of life, and life is the exam. What is the meaning of a simple exam? Someone will say that the life of the rich is easy, someone will say that the life of the craftsman is too difficult. But you’ll be surprised when you’ll find out that they’re both living their lives on their boundaries.”
