Keep reading the advice and the experiences of other gamblers. This surely helps in correcting yourself. Gambling is all about self-control. If you're good enough to have control over your gambling activities, then you can maximize your winning potential. Most of the time, gamblers used to win well, but they don't know when to make an exit or comeback. When you're good at it, you can avoid huge losses, and taking advice will help you overcome stress when you're at a huge loss.
If a gambler can understand these concepts stated by OP, and put it into practice, such gambler will not become addicted, and start chasing his/her losses. Another thing that a gambler needs to know is that, he should not always think of winning the next game, but rather he should have the thought of losing it, maybe this will make him to be careful with the amount of money that he wants to use to stake or might not place his bet anymore.
To be a responsible gambler is not easy because some people are very weak at controlling themselves in whatever they find themselves doing, especially when they are in profit. Some gamblers also don't know that they are addicted, which makes it a big problem for such gamblers.
Being able to control our budget is the best form of gambling responsibly, but most gamblers don't always look into this form of responsible gambling due to their interest in making more money while gambling. That's why they always go against the idea of limiting their gambling budgets. However, on the long run they tend to regret why they've been wagering without calculating. Such things has landed most gamblers into trouble and still, despite the regrets, such players will always wager more money on another session.
Hence, when gambling, looking into other people's experience can help a player determine what his fate would be as a gambler. Such things as reading Op's advice is a great way for gamblers to stay responsible, but due to their entanglement in the game, gamblers tend not to get interested in practicing what they've read before gambling. This negligence therefore lands the player into a problem gambling in a way that he wouldn't have enough to save for himself, he will lose out most of his funds in the game.
As you said responsible gambling is not simple, only a handful of people were able to control their urge for making more profits in gambling. And they enjoy this on the long term, because they lost only few funds and time. Gambling addiction doesn't get to such people and their emotions are always intact. Unlike other players who get compulsive and lose out every little thing they ever had, responsible gamblers, though not many in number, enjoy completely all the good things gambling has to offer, ranging from fun, to skills.
