The advice you highlighted is absolutely right, anything that can make one addicted to gambling, will also deprive them of their peace and this can affect their relationships. Sometimes, in life, making some decisions despite one's emotions isn't that they will miss their chance to win big, but to remain happy and preserve their relationships and trust others have in them. This is why, anyone who engages in gambling should be ready to accept whatever the result may be. That way, they won't get addicted or feel the urge to chase their losses.
Emotional decisions while gambling will lead you to financial losses as well as take away your mental peace and ultimately put your life in a state of disaster. Remember that gambling is just a part of entertainment, if you expect more from gambling, the amount of financial losses will gradually increase, as a result of which at some point you will lose self-control over yourself, which will lead to a beautiful life.
Only gamble with money you can afford to lose and set a time and money limit before you start gambling and accept the outcome calmly. Never gamble aggressively with the mindset of trying to win back lost money, as this will inevitably lead to financial losses.
