Op you are right. It is because they want to get rich overnight and they believe gambling will make that happen.
Gambling is not a short cut to get rich, the probability is very slim. Normally, whenever you feel like gambling, make sure you set a gambling limit. When you exceed that limit, stop immediately.
I will advice everyone to set limits in their gambling. It could be daily, weekly or monthly and make sure you adhere to it.
Just as I mentioned earlier, greed always leads to losses in gambling, and if you don't want to lose you must have self-control over your gambling habits and not expect too much from gambling in a row, this is very important and setting a time limit and how much you gamble within a week make even more sense.
No one should think that gambling is a short cut to making money, there is no easy path anywhere, whatever involves money needs to be hardly worked for, and that should be seen with careful effort and not some lazy ass thinking that they could become a millionaire in just one bet.
Agreed, there is no easy way to be rich. It requires hard work, and for some it is smart work. Very few get to be rich out of luck. We should never see those successful out of luck and expect the same to happen for us. What we need is to take the people who have made themselves rich out of their hard work and smart work and progress forward. This will surely help in the betterment of life. In simple terms, a businessman invests and makes good money for life. A gambler keeps spending, and someday he gets lucky, and life changes. If not, all the spending ends with pain. So, we need to understand and plan.
