The problem that often occurs for most gamblers is because they don't realize that greed is what drove them to loss.
And discontentment, despite winning whether small or huge amount, they won't just stop.
Therefore I agree that the most important thing in playing gambling is how to control our greed. Because this is what triggers a loss initially to spend all the capital
you have, only to get a win when playing gambling.
It's easy for us to control it but there really are severe cases for those gamblers that are having hard time for them to control it.
