Most people dont have any self control and tend to gamble more and more. They are just greedy and want more profits even after making profits. That is why they lose so much and end up in debts. However better you control it, its not for everyone. I prefer to use my skills and hard work to earn money and not leave it to my luck, so I hate gambling and for me gambling is a wrong thing. Others may consider it an easy way to make money and so a good thing. Whatever be the reason I still hate gambling.
It is not really a wrong thing when you can control it. I have been gambling for years and have never used anyone's else money to gamble or even find some excuses when I lose, I simply accept it as part of the risk. Point is that no one should be blamed for gambling, they should be blamed for getting debts for gamble
Yeah by controlling emotions, we must have a definite goal in our sight and the hunger to achieve it, yet not getting lucrative towards more winnings.
But the problem is that when we win our tendency and behavior changes, a lot of positive energy seems to surround us when we are winning and hence makes us feel like we can win more. So controlling temper or greed is quite impossible while winning.
