of course gambling was made for leisure but in the same time, people use money to get more interesting and then they make a bets with money. from this, i think in gambling, money is also everything because people wants to playing games with money involve and that money is for the winner, winner can takes all the money.
Usually we have what we called as beginner's luck and we have that ultimate fun because we are also winning but it's wrong to think that we will have that all the time, that's why it's called "luck" because it's not consistent and we should only be happy when we are lucky but don't expect too much.
Its the same with all addiction. If you're addicted to a certain sport, or video game, you don't really think about the outcome or the prize you'll get from winning. What's important is you're playing. When gambling, i don't think there are that many who actually plays to win. The happiness that gambling gives them would be worth every penny they lose
I guess people enjoy wasting their money in games like gambling.It is however not that important to me since I am poor and I keep my money and save it so I can invest it well and not waste it. Its seems people have different opinions about it. Again in gambling money is not everything and having fun is also there and so I guess as long as they have fun its good if kept under control.
