As far as I know there is no gambler who only gambles once a week because it is an addictive drug like cigarettes which is hard to give up. On the other hand you cannot earn certain money from gambling so it is not really ideal in your personal life. According to me rich people can gamble because they have enough money to back up but a common man can be destitute when he gambles. I gamble but when I have more capital it is a secret from the society and I don't always tell the family. I expand the money I earn from gambling into other businesses but always keep my thoughts straight.
