Why do unlucky people generally have mental problems?

Who said that? Luck and cleverness are two different things! These are two phenomena that are doomed by heaven, impossible to change and completely untouchable. Luck is external and cleverness is internal. You can't be lucky because of your intelligence. It is impossible to be unlucky because of poor intelligence. In fact, in real life, the opposite situation often occurs, that is, a person with high intelligence happens to meet with bad luck, which leads him to accomplish nothing and nothing. But only some people with low intelligence are often lucky and omnipotent. So, nothing is certain, let nature take its course.
