Use the smallest possible percentage for gambling from your monthly income even if you have a large salary out there while you increase the percentage then it is quite worrying because of the fear of increasing the amount of the percentage because we feel we have a large salary.
That's my current rule of thumb in gambling, depending on how I win in it: for example, I have won in any gambling and have exceeded the initial capital limit, then it will be set aside in gambling to continue some of it is withdrawn for other purposes maybe fun outside gambling.
If I lose, it will be put back a small percentage like the original plan above.
There is nothing that beat proper planning especially when it comes to anything thag involved money. When you see people say use a percentage from your monthly income(most often than not 1%), some others think it's an exaggeration but to be honest, nothing beat that in gambling. Sometimes, I will be just on Twitter having my normal time on timeline and then I saw a betting codes from a friend and I get tempted to bet on such games but when I remember that I have an allocation and I can't gamble more than that, I stopped instantly.
When you are limited with an allocation, it gives you time to think before pressing
stake or
bet because as soon as you bet that money, then you know it's not coming back, the coming is under a probability and doing unnecessary and wasting money on bets is limited, with that even addiction becomes very low as you don't even get chances of becoming addicted gambler.
