This might be an impossible thing to accomplish, it's easier said than done. Personally a good reason for me to quit gambling is due to the negative effects it has. It doesn't matter if you win as long as you are constantly involved in it you will definitely lose everything you have won including the funds in your bank account. This makes me wonder, what's really the point of gambling and winning in the first place if you would still lose everything?
Losing in gambling can affect your temperament and also your relationship with other people, it can also lead to depression which is totally not a good feeling. Quitting isn't easy but if you can get it done make sure you do it.
It is not an easy thing to be able to get rid of the desire to gamble, moreover, we have done the gambling activity very often and correctly, as you said, it will indeed be very easy to say and only a few days later we will still be back to gambling.
I think it will be very difficult to be able to win gambling continuously and what we often get is that those who have found victory will again experience defeat because they cannot stop when they have won, it is useless after we experience victory but lose again when continuing to bet then in betting it is very necessary to be able to control ourselves so as not to suffer big losses in gambling.
You're right, when someone loses on the bet they play, it will certainly make them emotional and they can do unpleasant actions with the people around them, everyone certainly has the desire to stop when they lose but when they have money they will go back to gambling, it takes effort and also support from the people around us to stop to get rid of the habit of gambling.
