I don't like regretting my actions because there is nothing I can do to change it. OP is unhappy that he cashed out because he could have won higher if he had left the game. But we fail to recall that sometimes cashing out is a good option because the game might end up unfavourable. If the said bet didn't play like it happened, OP would have regretted that he didn't cash out. Some gamblers are high-risk takers who are willing to take any form of risk just to win the highest stage.

So it needs to be instilled in the mindset of always being complacent about what has been obtained.
People who are too greedy and always lack with the victory produced, let alone it is a big victory, in the end it will only be a looming defeat.
Seeing some gamblers who are just squandering their money in pursuit of uncertain winnings, they don't have any guidelines.
In the end, they will lose it all and regret it.
