And as we can see, there is the 10% for hobby and recreation which can be allotted to gambling. So, by having that percentage, we can say that we're already a good budget manager of our salaries. Not just that, we need to be consistent and won't shoot out with the allotted percentage for gambling/recreation.
Some people may be consistent, but most who do this kind of budget implementation will be affected because their psychology is not strong enough to resist the temptation to bet more.
10% of the salary is for hobbies and recreation, gambling may only be about 5% and that is more than enough if you only play for a hobby.
But if the allocation limit is exceeded, all the budget allocations will be chaotic, not disciplined in the management carried out will only cause losses.
