Gambling only gives joy after a game has ended,and it ended in favour of you, especially when you were expecting a huge amount of money,and you finally won it,you will be very excited for that
If you gamble, and not get any kind of emotion, just place a bet and repeat, until you run out of money or time, they that person is doing something wrong. I think every gamble feel excitement during time when bet is placed and bet is settled.
You say that «gambling gives joy only in the end and if you win», but some people like the process in general. For example when something from my electronic devices get broken, I feel excitement and joy trying to fix it myself, when I can call master that will fix it quicker.
I personally like that moment of gambling, when you dont know the result and wait for it. Sort of a small mystery or secret for tiny money.
Maybe it is something new to people that are not in gambling or they just gamble a few times in their lives that they can say there is only joy in gambling after winning and then there's pain when losing. I believe this is something wrong, if a person only found joy in winning and then pain in losing it obviously means that someone is betting money that he or she cannot afford to lose. We only need to bet small amounts of money so it won't cost us pain if we lose.
Indeed, there is more thrill and excitement when betting especially when we're watching the games live.
