Well, the way to stay responsible is by following the next rule:
Never bet with money that you can't afford to lose.
If you always gamble with money that you can lose without getting in troubles then you will be fine in the long run, but when you start using the house rent or the money for food on a casino, then if a bad streak get's you it will be a complex problem.
And you have to decide what's the goal, it could be to have fun or make money, if the goal is to make money then big bets is the right way, even if you only have 5 attempts.
Its always been the GOLDEN RULE not only on gambling but also in investment on which you should really be just only spending on the money that you can afford to lose and never ever make yourself
spending up on your life savings or emergency funds on which it would really be that compromising your living. Being responsible isnt really that hard as long you do really just make use of your own common sense.
It is really that impossible that you cant really be able to think on what are the things that needs to be done sensibly specially in talks about life savings or funds which on the time that you are seeing that you are affecting or making use of it already just to cater out with your gambling addiction then this is something a problem that needs to be cut immediately or else then you would really finding yourself on great trouble.
Gambling should really just that for fun and not for money making or income because once you do have this kind of intent on mind then you would really be that having a hard time
on getting out with those kind of actions which it would really be that getting in line with those kind of impulsive spending because you do have that idea which instilled out into your mind.
Being responsible might sound easy to hear or see but applying it would really be challenging if you arent that wary on the actions that you are making.
