Many persons have been gambling for more than 10 years without seeing more gain that their have lost in the past years.
I have a friend who has vowed that he must get rich through this gambling which propels him to be staking everyday a day will not pass that he will not show me a coupon and i have been very worried about this so i dont know if i should tell him to stop dreaming of acquiring a big house a nice car good clothes with gamble money.
Gambling for more than 10 years without any gain is enough to tell them that gambling is not for profit making but rather for fun, and anybody who gambles should do that with funds they could afford to lose, and also they should do away with the mindset and mentality of gambling as a source of income otherwise it is the beginning of their way to addiction.
As for your friend, he may be addicted to gambling, looking at the fact that he made such a statement, and hoping to achieve those statements he has made through gambling is unrealistic to say. You just have to help him immediately, otherwise it might be worse than what we are discussing here.
The earlier you talk to him about the principles of gambling, the better; otherwise, he might be doing this, thinking he is helping himself, but the reality is that he is doing more harm than good to himself, thinking he wants to help himself through gambling.
