Many here voted for profits and its ok but I think if you see gambling as another source of income, there will be a time that you will become greedy and will invest more money in gambling which is wrong. I think lets just gamble if we need some thing to make us happy. Just gamble for fun only,.
The key reason for gambling varies from person to person. There are people out there who eye on money and would gamble for nothing but money. This is something you will get to see in every movie based on gambling like Casino Royal and 21 etc. The pursuit of riches is the sole motivation and reason for a large number of people to gamble.
