The best way to gamble is to gamble for the fun of it and not to make money off gambling, I know this is hard for most people but taking money away from gambling will give us great satisfaction so for sure to gamble on the safer side we need to always check the limits at which we put profits in front.
Having a responsible gambling life is a lifelong journey that requires discipline and dedication to apply all the roles that keep you on the safe side while gambling.
You are absolutely correct that is the real truth about it, because as a good gambler once you see gambling as an entertainment or having fun you wouldn't experience any much losses in gambling. Already as gambler we most expect winning but let it be something that we don't rely on, so that even if we don't win will would be able to control ourself without panicking.
Gambling for fun reduces the desperation to win and it'll make you to feel relaxed while gambling. I don't take gambling too seriously and that is why I use small amounts for it because I know that wins is by luck, not because you are too perfect. Responsible gambling for me is to have a budget for it and be disciplined not to exceed it because gambling can be addictive if you don't have self control. Lack of control in gambling is what causes irresponsibility and that is how a gambler will gradually drift to becoming addicted. Control yourself not to chase loses or be overconfident to continue when winning, know your limit for the day and stick by it
