As a gambler,I know that we have done so many mistakes in the pass base on our bets and wrong strategy or calculations that we have done which led to losing the game that was suppose to make you win big.
Greed is the gambler's biggest enemy in the gambling world. When a gambler gets greedy his chances of losing will increase and it is hard to find gamblers who are gambling but are not greedy. There will be temptation in gambling but if it can be kept at a controlled level, the gamblers will be able to conduct normal gambling activities. Personally, I have been greedy myself and lost a lot of money because of it. I erred when greed was at work in me. If I hadn't been greedy there I wouldn't have been wrong. So if greed can be controlled, one can be saved from making mistakes.
Greed can be control if you know how to play safe and wise, there are many instances that you can quit and stop your game after winning decent amount of money, but because of greed instead of quitting you did try to keep pushing for more thinking, that luck is on your side and you can continue winning.
The rest will be the story of regret. All those "what if" things will come out after that session. If you only control that, greed maybe
you are enjoying your profits and not regretting the amount of money that you let go from that sessions.
