Those who risk a lot on gambling are doing it to make money only, those who aren't too concern about making money spend their time to add fun deriving from the games they play, in return they use small amount of money all the time.
Also those who responsible gamblers are not asking much from gambling, they want to have good time and also make few money if possible, such people will never get intoxicated by gambling.
Depend on your jobs, learn trading, invest your money in good assets and hope for the best, be a gambler who don't want his life dream fulfilled by gambling, it could still happen but don't depend on it from gambling, it's too unrealistic.
Money must be made by man, but not through gambling, some days luck might smile on you, but its more thrilling when you don't expect anything from it.
Gamblers should learn to honest with themselves, if you observe that you attach much emotions in it, and it makes you spend more, you simply quit as its not for you. You can do other things for fun, perhaps things you've more control over. Different things work for different people, and if gambling is destroying you, I think its right to save yourself first.
