Why is fortune telling always inaccurate for good things, but so accurate for bad things?

Nine times out of ten, life is not satisfactory. If you don't tell your fortune, something will happen. Unfavorable things account for a large proportion, and when they happen, they are considered accurate fortune telling. When the proportion of satisfactory things is small and the probability of occurrence is low, it is often considered inaccurate. I don't want to tell fortune, but I am willing to study. Through learning, learn to know yourself, know your strengths and weaknesses, strive to carry forward your strengths and try to change your weaknesses.
