In this case, you have to shape your mindset in such a way that you can satisfy yourself with a small win and withdraw money. When people win a little, they become more greedy. They think of gambling more through them and think that they will withdraw huge money after winning a big amount. But their expectations are never realized, rather they become victims of reality and lose them too. You have to have the mindset of enjoying the profit if you get some profit, if you get greedy, it will be lost, and every gambler should try to understand this reality well, even if you lose, you have to accept that loss and stop gambling, otherwise the loss will continue to be huge.
Greed is something that makes us make many bad decisions , it makes us unleash all our impulses and emotions so we can't control them, it also allows a person to become uncontrollably excited and temporarily lose their mind, and that's something we as people must manage. Money can be controlled , but we must put greed as a last resort and always appeal to reason and intelligence at play.
Need to be wise in terms of controlling your greed not easy at all but can be done if you keep practicing to limit yourself with the set plans that you create, for sure there are limitation that you can put in while you are still in sessions, things that can help to avoid greed to dominate inside you.
Once you understand both risk and opportunities, it's about making good decision and not putting down your support to keep yourself in-line with whatever strategy that you are following.
