It's tough to realize that whatever action you take, it's your sole responsibilities and no one else should be blame from your action, is your decision and it's your money to take care.
And many gamblers don't see it and don't want to blame themselves. They all think that it's just this and that for any reason, if the outcome is good, they should be praised for it with their bets. But if the opposite happens and they've lost everything, it only means one thing to them and that's on how they should criticize themselves. Because taking responsibilities is being avoided by most people nowadays and even gamblers, we don't want to take accountability when we're losing money because we think that it should be on us. It's already a sign that person is an addicted gambler and don't want to get blamed for their own actions and decision making as they gamble.
Honestly, some people are naturally irresponsible and I categorize such people as individuals who shouldn't gamble because there's no way any gamblers will want to be profitable in gambling and won't take the blame if everything goes south. Which I believe is the personal step in controlling one's buzz aside from guidelines provided as a means to gamble profitably.
People who blame others for their mistake are those who are mostly gambling addict because they won't accept the major concept of the game which is the house is always favor in every game.
