Indeed. And no doubt that many gamblers become greed especially when they win. The will to win more will come to them and that makes it difficult to stay away from the temptation of gambling. They will forget to reduce the tension after winning so they insist on continuing to play without thinking about stopping for a while.
There is something that people say that you should be very careful after a win because after a win is usually a time that people can forget themselves and ignore all the discipline that they have been practicing. Winning in gambling should not be an excuse to automatically change your gambling habits, to do things like increasing the budget or amount which you gamble with.
After a win, especially a huge one, a gambler should take some time off from gambling, to evaluate their next action, and plan properly for the amount of money that they have won.
If you take some time off, and even spend some time away from the pressure of friends and family, chances of making better decisions increases significantly.
