In ancient times, there was a Hercules in the countryside. His father asked him to buy dozens of Jin of eggs in the town.
Father handed the basket and pole to his son, and specially told him that the Pole had just been finished, and it was estimated that it could only bear 80 ~ Weight of 90 Jin, you must not buy too many eggs. The Hercules promised.
But when he arrived at the market, he forgot his father's exhortation. The egg vendor told Hercules that the more eggs they bought, the cheaper the price would be. Hercules thought of his strength, and it was not cost-effective to pick more eggs at a time, so he bought a total of 100 jin of eggs. But when he just bent down and picked up two baskets of eggs, the pole was broken with a sound of "bang. It is conceivable that the eggs in the basket were all broken, and the Hercules failed.
"Hercules" who give up the 90 points that they can get stably but take the risk of getting zero to get 100 points can be found everywhere. Of course it is good to pursue the maximization of interests, but most of the time it should be enough to stop. There is a saying: "best" is the enemy of "good", which is the truth.
