What's the difference between a rich life and a happy life?

Literally, these two lives are different.

"Rich life" means that a person lives a rich and expensive life. In your life, there are times when you are rich and expensive, which shows that you are a person who can make a fortune and be in power.

"Enjoy a happy life" means that a person has a happy life. No matter what happens in your life, you don't have to worry. Everything will be smooth and safe. As long as you sit back and relax and enjoy it, you will enjoy your life.
