Greed is not good, I know of many people who have been to casinos and annoyed a lot, but suddenly they get the greed to win more, no matter how much the other players tell them not to play anymore, these people continue playing and their winnings turn them into losses, and I think that is worthy of a very foolish person, after having a lot of money in their pockets having to leave the casino with nothing, not even a 1usd is something that is not worth it, greed is something difficult to manage, but in my case I feel that I do not have that greed, I take great care of each USD, sometimes I try my luck in some casinos, but only that, it did not happen to me, because I can lose everything.
Being greedy is not good all the time but there are times where greed will be use in a right way. It can help you push more to achieve something that you have been dreaming of. If they are annoyed and don't like the fact that they are losing then they shouldn't continue longer or they shouldn't play gambling at all.
There is no other people to be blame there but only them because they keep on repeating the things which are wrong. For some, greed is difficult to manage but for the other, they can manage their greed very well. It's okay for them to play gambling using small amounts and they can choose if this purpose is either for fun or for profit.
