I also think that you can play only when you understand how much you can afford to lose without consequences for your mood, if it is 10 dollars, then this should be the limit amount for the game (per day or per week, everyone decides for themselves). If for someone the loss of any, even the most insignificant amount causes discomfort and affects the mood for the whole day, then such players are better off not gambling at all, because losses in gambling happen quite often.
Yes, that's basically it, it doesn't matter if it's little, it could be 10 usd per week , it's not a reason to be ashamed, one of the mistakes that I've noticed the most is that if a Player has 10 usd per week he wants to be on par with others who can spend 10 usd in a quick moment , but it's because of his financial capacity, the worst thing a player can do is compare himself with another in that case, because that financial capacity is not Possible since if he does that and loses Repeatedly that's where all kinds of problems begin.
