Gambling teached me how to be nore responsible and aware about the value of money,since the moment i start earning my own money,I learned how to gamble enough money from my extras,and not from my hard earned from this I valued every single scents that entering and coming out my pocket,but i dont literally say hat all gamblers can be like me because most of the people i played with,they become addicted and until now being engaged to illegally activities
Someone who started to earn hard with his money will definitely won't spend that for something that its not worth of or he can't avail to see it going into pieces and started to disappear. Just like in gambling, the benefit you mentioned was about on how you can properly handle your money and it's good to know that it had taught you that way.
Extra or hard earned money, there's no difference if you are valuing your money much.
Majority would think that the benefit in gambling is when you can bag money.
This is not the case for some, for some people who have matured and learn their lessons in gambling, when they are so aggressive, it's their emotion that plays hard, and it's not a good strategy and I don't even all that a strategy. When we act based on our emotion instead of our mind, it will be a disaster in the end.
