There should be no much lessons to attend in order to be able to learn how to be a responsible gamblers other than making sure to use funds that we can afford to lose to gamble and not also entertaining the idea of getting rich through gambling. I think these are the simple factors that determines responsible gambling, because if you don't lose more than you can afford to then you wouldn't be having a need to chase losses, and if you're not among those that takes gambling as a means of getting rich then there's nothing you have to do with impulsive gambling at all cost.
That should be the basic motto in gambling. Gamble when you have extra. And not because you want to find extra funds. Because most gamblers have the mindset that gambling can either give him the jackpot or will give him the huge profit that he's aiming for. However, we all know the end result of most of our games.
The problem is that we don't know when luck will strike. Even if a gambler comes with the intention of doubling their winnings, it doesn't mean they can't win. However, as I mentioned above, that's why we shouldn't gamble for entertainment. It's not impossible, but we certainly don't know whether we'll win or not.
Furthermore, gambling with the intention of making a profit will only damage our mental and psychological well-being. This is because when we expect to win but end up losing, we'll inevitably become emotional because we've lost money instead of making a profit. Essentially, throw away the idea of "doubling your money" from gambling, because that's the beginning of disaster.
