Gambling can have good and bad effects on ones life. If anyone play and win in gambling you can't even imagine how happy he would be of getting quick money.
On the Other hand if one lose in gambling, and the amount is good, then one can be sad or even depressed.
Playing and winning will definitely provide happiness for someone who faces it. But, will the person use the money he gets from gambling to buy or to cover his needs in real life? As I can see based on the experience of friends, they prefer to use their winning money to gamble again and again which for sure will give a huge chance for them to meet the sadness at the end. I mean, winning can be a temporary pleasure while sadness is the ultimate goal for people who are addicted to gambling.
Most of the gamblers keep on playing until their money last, win or lose they will stay and this behaviour is not good in gambling. When we taste the win, we forgot how to take profit and becomes more greedy and at the end of the day most of the gambler failed to win because of the lack of control to their self.
