yes.. I often do that, when my target hasn't been achieved I keep playing and hope that my target is achieved but everything runs out before I reach the target.
It is difficult to find a definite formula so that we can control finances and greed. Maybe we can only use feelings, if we feel that our luck is not good, we should stop playing and withdraw the remaining money before it is all gone. But it is always easier to say and very difficult to practice.
It is common for many gamblers when they have a winning target that they want to achieve. But in reality, achieving their winning target is difficult because their money runs out before they can even win. We can only limit the use of money if we have a winning target that we want to achieve because that will make it difficult for us to get it. Apart from that, we also don't know when luck will come so that we can win the gambling game. And even if we keep trying, it also doesn't guarantee we can win because this is gambling where someone wins and loses.
Exactly, you can't control that in terms of luck though experienced may allow you to assess the possibility I mean can give you some hint to whatever next steps you need to do either to avoid losing a lot or to quit while you still have some decent profits, emotion is your killer when you are into this activity, most of the time greed dominate you, thinking that you can earn more if you will keep pushing and aiming for bigger profits instead of quitting and enjoying small earnings.
