Why do people go crazy?

Sometimes, people go crazy. Why? Because he won a million in the lottery, he went crazy. I got a million for no reason, so I was crazy. The thief originally only wanted to steal a box of matches, but after he got it, he opened the matchbox and looked at it, and the matchbox was not a match, it was a diamond ring, so he was crazy. A civil servant was supposed to be promoted to deputy section chief, but because the section chief died of a sudden illness, the superior temporarily decided to promote him to section chief, one step two levels, so he was crazy. A man went to the bank to withdraw money, the bank salesman was negligent for a while, paid him ten thousand, he thought that he had ten thousand in vain, so he was crazy. All these and so on are not normal things, but all abnormal things, there is a mystery behind them, and once the abnormal things are corrected, Zhang Madness will become a curse. The dead section chief left a suicide note, and the suicide note said to the organization that so-and-so had been examined by him in many ways, had good conduct, and had strong professional ability, and that he should let so-and-so succeed him after his death, fortunately, although the civil servant who was preparing to succeed to the throne had not yet been announced,,,,,, the cashier had squandered the ten thousand yuan that he thought was white, but he received a refund notice from the bank,,,,,, but anyone who was happy and crazy for the unexpected harvest would not have a good end. Therefore, to be an ordinary person, to do ordinary things, not to try to make unexpected profits, and even more can not hope that the pie will fall from the sky, with an ordinary heart for normal things, it is common sense, and only then will you be at ease.
