What does this sentence mean? tell sb's fortune

I used to be a fortune teller. In fact, this thing is the same as Buddhism. If you believe in it, you will have it. Don't believe it or not. Simply put, if the fortune teller tells you something good, such as your recent good luck, don't say it. Happy, there will be a happy mood, happy psychology. If he speaks ill of you, you don't have to worry, and you don't have to keep thinking about these problems. You just need to be yourself and be the best you can be. A simpler sentence is that if you believe in fate, then fate is your master, and it will always influence you. If you don't believe in fate, then you are its master. I am simple, right? You have to understand. In this way, I wish you happiness all the time, and don't be influenced by your imaginary bad mood.
