Use AI more often to eliminate all your prejudices and illusions. You can ask this friend a series of questions, such as whether the US stock market will fall, the cryptocurrency bull market will continue, the Chinese national football team will win, and whether he still loves me. If several friends ask together, life will not have too many worries, because you will soon realize your own weakness and the rapid development of the times. Try to learn as much as possible and enjoy the moment.
