Yeah, it's the best solution for him to re-assess whatever mistake he made during that failed session, instead of pushing his way to keep playing and most of the time the outcome will be against him, you need to be wise to keep that emotion and treatment towards your gambling participation, having that kind of understanding will let you to keep yourself in shape.
By introspecting ourselves on the mistakes we have made before, this will certainly motivate us to be more careful in every decision and action we take in the future. For wise and responsible gamblers, have good thinking because opportunity does not come a second time and this can be applied in gambling so that we remain consistent in maintaining good control.
He can check any mistake he made to know how to fix it, and it needs patience to search for the way to change himself not to be like that when he lost in gambling. That's normal if someone behaviours change based on what he faced but doesn't mean someone will still be like that, especially if that person realize that his bad behaviours made him feel guilty about what he made before. That's why awareness is necessary needed for every people, whether they are gamble or not gambling to do something because that can make other people feels not comfortable with him. Introspecting ourselves purposes to know and identify the mistakes so we can fix and change to have a better person. If we can do that, we can suppress our emotion not to doing anything that can make us feel bad after we realize.
If we can adjust well then yes it can be done, more on your self reflection and how to find the best adjustment that will work for your attitude towards gambling, like what I've said, re-evaluate yourself and think about that previous mistake in order for you to bring the right strategy when you think that you are ready again to play the game, though not all can do that and will just repeat the same mistake and the sure thing is it will affect his attitude and his behavior especially when the person is on the losing streak.
Most of us gamblers probaly have experience that, but it's a bad attitude mate, it's like we aren't good in accepting our losses and that we would involve other people with our disappointment in gambling. It normally happen when we aren't gambling for entertainment only and we do risk money more than our budget, I would not use "money you can affor to lose", as there are times you can afford to lose the money you are gambling but it's already out of your budge, so in the end, it will have a big effect on your emotion.
You are right. Your gambling emotions reflects only when you have a personal motive towards your gambling and you must have been staking above what you can afford to loose.
The Op is being overwhelmed by his winnings and his losts so, whatever outcome he gets from the gambling is being related to his emotional actions.
If only you can stake with what you can afford to loose, either your excitements or your aggressive emotions in your casual life wouldn't be associated with your gambling life talk more of involving your family out of it.
Yeah right, whatever the outcome it reflects to his atitude how he takes the result of his gambling reflects to his mood in each time he play the game, controlling your emotion is very important as it's also your key to avoid losing huge amount of money.
