Losing in gambling gives you fear and tension so if loss in gambling just leave it if you don't leave it gives again losses only so gamble with intelligence and patience it is the only way to survive in gambling .
It is inevitable that when you gamble you will tend to lose and more you play more you will end up losing . So if you can bear that pain then its fine else if you have a weak heart then forget about gambling as it is not meant for you.
I agree with you that if you can bear the pain from the consequences of gambling you can continue doing what makes you feel happy. If you are soft hearted better stop doing it and focus on something that can help you to save your money not to lose all your money in gambling.
It is always a matter of choice on how you want to live your life. But I would suggest to you that if you dont have enough money to support your pleasure better stop now dont wait for the moment that you only have small amount of money. There are always what if's in life we cannot predict what will happen tomorrow, especially accident. How you will survive if you encounter such things?
