we must control our greed and learn self-control. If we do not have control over ourselves, we will easily become addicted to gambling.
There is always something that stops us from falling and I think that most of us agree that when greed comes in everything starts to fall, that is where our discipline has to be the strongest, because with good discipline there is no way that any kind of greed or any kind of temptation that is always present can come in.
You are right but humans can not be 100% discipline that's why most times disciplined gamblers also fall into temptations. But even if one can can be tempted by money through loss chasing at least they should try to control it. If chasing loss becomes a habit it's very important to take a brake on gamble rather than continue then lose more everyday.
