What does fortune telling mean?

The fortune teller said that I would get rich at the age of 34. Can you believe it?

Yes, as long as you believe you will get rich at 34, if you don't, you may get rich at 30. I have calculated my life, and fortune-telling is actually the Barnum effect. In other words, fortune tellers state general facts that we usually don't pay much attention to, and their words are very general. For example, when I was telling my fortune, the fortune teller said that there was a school near my home. At that time, I thought he was accurate, so I continued to let him calculate. Later, I spent half a day visiting many places in my city. I found that there are schools near all communities. In fact, the fortune teller did say it in general. First, he did not point out what kind of schools, kindergartens, primary schools, middle schools, universities, technical schools and even some training schools can be regarded as schools. Second, he did not point out the specific definition of nearby. How long can it be defined as nearby?
