As we see gambling falls into two category:first is you win and other is you lose.
It is not predictable, also it doesn't count your efforts. So if i were you do not gamble if your money is just limited. Gambling is just a matter of luck so if you are just looking for fun do not wait your money on gambling it will not help you to gain money.
I agree, because once we gamble and we just have a limited amount of money to play we can possibly lose all of it and nothing left to us, it is hard if we just have limited amount in our pocket when we are playing once we get attached in the game it will be hard for us to stop it immediately even if we don't have enough money.
You should always carry the amount in wallet which you can afford to lose in gambling. So once that amount you have is done you would not gamble or think more about it. Also another thing is that rational person would realize if its their day or not and then accordingly you can continues or stop it.
