Controlling yourself while gambling is hard, especially if you are enjoying the game from your winnings and if you are experiencing a lose streak that you can't get back all of your lost,
that is obviously Greed is what you are talking about,sometimes the love for money is what brings us failures,so many times that we are already winning but we don't find it enough so the thing is we demand for much more.
No, it is not the love for money, it is the needs and our own mindset of money is all that we need. It drives a person in everything when it comes to money.
that is why a lot of gamblers are greedy and ends up getting addicted to it.
and that is what we need to overcome,not just a controlled mindset but the Lust and Greediness in which part of characteristic and not just an ordinary attitude.
Which is really hard. There are some people who can overcome it, but most of the gamblers, they just end up in the same direction where they will become addicted to it.
I think the best way to control yourself while gambling is by limiting the amount of your money to avoid spending a huge amount of profit and to continue to play.
but if you have no control this is impossible because we will always seek for opportunity to get/provide money to play still.better to prepare our self first before getting into deeper gambling habit.
It will only become possible if there is someone that will guide you and stop you once you can't limit yourself to gambling. Having self-control is hard but with the help of someone dear to you, it will become possible.
